I made a little script that extracts some info from the signup database and imports it into userpages on the wiki, so now almost everyone has a userpage on the wiki. Also, it’s possible to log in to the wiki with your signup account’s username and password again (it was disabled for a while after upgrading MoinMoin). Feel free to try it out, log in and edit your userpage!
Go to Wiki login, log in with signup account info, find your userpage (Userpages) and click Edit under Wikipage in the menu (you have to click on the header/arrow to see the Edit link)!
Edit, 26 Apr: Wiki login with signup account should work for real now 😉
