Re: WP & bbPress integration: what would you do?
The latest versions of wordpress and bbpress are the most secure and bbpress is designed to integrate with wp. The only possible advantage to keeping an older version of bbpress is the amount of plugins that have not been updated to ensure compatability (in other words, if you want a lot of plugins, stick with 0.9 until the ones you can’t live without are brought up to speed. My recommendation – upgrade now that you don’t have too many plugins to worry about).
If you’re going to upgrade bbpress, do it first.
Install wordpress and integrate with bbpress. Basic (shallow) integration eliminates the need for users to log in to each seperately.
