Just thinking. Would it be possible to have people setup only one account and have it work automagically everywhere PARPG related?
For the beginning, we could try to use an AuthPlugin for mediawiki. On IRC i was told that this works - if I get the ok, I am going to spend some time researching how this is done.

In theory I think giving people one shared login is better than require of them to register multiple times (forum, wiki, trac, and at cvsdude)
