User:Bob the Test

In other languages you have to replace "Special" and "Main Page" with the words that are used instead of special in your language like "Spezial" and "Hauptseite" in a German wiki, otherwise nobody will be able to create an account.

To further categorize users based on their interests, you can set up MediaWiki:Requestaccount-areas. This should be in a format like:

   *Topic|Topic wiki page|text to append to all interested users' bios |text to append to all interested users' bios in group0|text to append to all interested users' bios group1|text to append to all interested users' bios in group2|...

These group numbers are based on $wgAccountRequestTypes. So if 0 is the index for 'authors', then 'authors' interested in a topic will have the group0 text appended to their biography. This can be useful, say, if users can be approved as either authors or editors. Authors can have "category:X authors" where X is a topic, like "mathematics", and editors can have "category:x editors". You can have as many groups as you want, but you need at least one.
