I have already begun integrating a wiki at
wiki.noblood.org. A 'couple' of things to share.
I have decided to limit editors to 'registered' users. This goes again wiki philosophy but we are not 'that' comfortable yet. BUT....
What to do about managing two different user tables, etc. We are going to explore requiring a wiki registered user to be registered at the vb site. We do that now with link to OSCommerce. When they go to OSCommerce, it first tries to log them in from the forum before continuing with Store. Still rough around the edges but it works.
In theory, when a user tries to create an account, it takes them to the forum and then returns them back to wiki. Remember, I just thinking out loud here. That means that they would have a vb user account AND wiki account.
The only other viable option is to have an OPEN wiki and not worry about vb users. But then you lose many of the benefits that make vb such a strong community builder.
