Since reshare-requests are already on todo I thought of something... bigger ^^:
Why not combine the two? Something as simple (explanation-wise) as anidb-account = forum-account
I'm sure that it's (technically) not that easy and involves some planning, like "how should the registration-process work?" - since it should be kept as easy and fast as it is now ...
I mainly want to ask if there are any major reasons to not do so

Advantages:
* No need for a second logon -> More people/participation in the forums? (or the other way round if someone just wanted to register for the forums without an anidb-account)
* PM-system for asynchronous messaging (as opposed to IRC)
Disadvantages:
* Might make the registration more complicated and thus scare "let's try it"-users
* Accidential public Chii-auth becomes more dangerous (from 0.01% to 0.02% ^^) - I mean those "7Msg Chii[AR] auth ..."-messages
* Migration most likely involves some manual checking, since not everyone could use the same login-names
