Re: what are the issues with wpmu & bbpress?
There seems to be a bit of difficulty with integrating wpmu with bbpress.
I disagree. You pretty much drop three lines into the config file for bbpress, use the same database and it’s set.
The two lines to share the cookies: Link
And this line to use the user table from wpmu.
And IIRC, that’s already in the config file, just commented out.
Hope this helps,
