Newsgroup Browsing

What is a newsgroup?
Usenet uses a hierarchical scheme to organize content. A newsgroup is a grouping of related subjects in Usenet.
How do I find a newsgroup to browse?
You can search for newsgroups from the search bar by selecting Find a Group and entering some keywords. A list of newsgroups that match your keywords will be returned. You can double click on the result to open the newsgroup.
What am I looking at when I browse a newsgroup?
In Usenet, users post articles. Due to the flexibility of the system, the way they post the articles can differ widely. Files can be split across multiple articles, a single article can describe multiple files, or a single article can map to a single file. When you are browsing a newsgroup, you will see rows of files made up of any of the aforementioned combinations.
How do I get more article overviews?
From within a newsgroup, there will be a partially shaded bar above the list of content. This bar is known as the Get More bar. You can select a region from the Get More bar and get that range of article overviews, or just get the default amount by clicking on the Get More button.
How do I update the newsgroup with newer articles?
You can download new article information by clicking on the Get Newest button.
What am I looking at when I select a particular message?
When you select a message from within a group, the content pane will appear and show more information about the specific post that you selected. Image and message posts will automatically be downloaded and displayed in the content pane. Binaries will not automatically be downloaded, but the content pane will show you enough information for you to decide whether or not you would actually like to download it.

Searching Usenet

What is a Usenet search?
Because Usenet is organized into newsgroups, content is inherently partitioned around a unifying topic. A Usenet search will find any matching content across all groups for any keyword you supply.
What is the difference between "Usenet Search" and "Mimo Usenet Search"?
Mimo leverages external services for search results, so doing a Usenet search will have matches returned by one of our partners, whereas doing a Mimo Usenet search will have matches returned from our own search service. Depending on the keywords you enter, results may differ from each service.
Why can't I find what I'm looking for, when I know it exists?
This can happen for multiple reasons. Most likely, the author of the post did not adhere to standards and conventions. Both search services use pattern matching on the subject lines of posted messages, and this places a lot of responsibility on the author to stick to the conventions that are in place. If you can't find an article, you can also try looking for it by browsing the newsgroup if you know which one it was posted in. Many posted messages are cross-posted to a few related groups.

Downloading Files

How can I download files?
You can download files while browsing newsgroups or after performing a Usenet search. In both cases, you will click on the download button (a green downward-pointing arrow).
What is involved in downloading files?
The process of downloading a file from Usenet consists of the following: downloading all of the articles that each file is composed of, assembling the disparate articles into a file, verifying that the file is complete, recovering the file if it is not complete, verifying recovery is possible, and automatically deflating the file if possible.
What is PAR2 verification?
PAR2 verification is a step in the download where the files that are downloaded are tested to ensure completeness and that they were not corrupted during transmission.
What is PAR2 recovery?
PAR2 recovery is a step in the download where the downloaded files were determined to be incomplete, and the recovery step will fill in the missing bits so you get complete, valid files.
Where can I turn off PAR2 recovery?
You can turn off PAR2 recovery from Downloads settings. This is accessible from the Tools > Download Settings... menu.
What is RAR Expansion?
RAR expansion is the process by which compressed content is deflated to its original state. RAR is the de facto standard format of delivering compressed content over Usenet. RAR expansion is the final step in a download.
Where can I turn off RAR expansion?
You can turn off RAR expansion from Downloads settings. This is accessible from the Tools > Download Settings... menu.
How can I download large sets of headers?
Retrieving large sets of headers can be done by click-dragging your mouse on what we call the "get more" bar — the grey bar at the top with a slice of blue. Click and drag to select a region on that bar and the "More" button turns into a "Range" button. Click "Range" for Mimo to retrieve the headers for as large a group of headers as you select.

Posting Messages

What is an identity?
An identity is a way for other members of the Usenet community to recognize who you are and one way for them to relate the content you post. You can use your real name and E-mail address if you like, or pick a pseudonym if you don't want to use your legal name.
Where do I set my identity?
You can set your identity by clicking on the Tools > Identity Settings... menu item. If you set your name to be John Smith and your E-mail address to be john.smith@example.com, your message posting identity will read: "John Smith".
How do I designate the group to post my message in?
The message editor that appears when you click the Tools > New Usenet Message menu item has a place to input the newsgroup you would like to post to. Next to the Group label, there is a drop down box that you can use to select the newsgroup if it is one of your Favorite Groups. You can also directly type in the name of the newsgroup into the text input if it is not in your favorites.
Can I post binary content?
Currently you cannot post binary files. However, we have this feature slated for future versions of Mimo.
