Re: Version of bbPress required to integrate with WPMU?
Depending who you ask, everyone will give you a different response.
It is my experience that using bbPress 1.0 Alpha 6 will yield the most positive results.
Remember however that bbPress also is not 1.0 yet, and that you are still going to need to babysit it and upgrade it and help it play nicely with any application you choose to integrate it with.
Because of the efforts of some bbPress users, they’ve created plugins and hacks to help more tightly integrate the 0.9 branch cookies with WPMU, but in my personal opinion you’re still taking a step backwards by using an older version than what’s available. Using the 1.0 branch will help better prepare you for what is currently happening versus what has already been, if that makes sense?
