I've seen this as a MOD but now that phpBB 3.1 does not use MODs I'd like to ask for an extension about it. The extension should work like this:
- User creates an account at the phpBB forum.
- That account is stored in the database where the forum and the wiki are.
- So that the user can enter the same account details at the wiki login and have their account ready.
There's no problem if you reverse the login (create account at the wiki, use it at the forum).
