Yes the roles integrate in 0.9.0.4.
The private message plugin has nothing to do with WordPress – it’s a bbPress plugin. However, there have been some security issues with it recently and you might not want to use it right now until those are ironed out.

hey, thanks but does the private messaging plugin work with the new alpha? just want to know.
thanks
I was searching on the forums but found not response. When integrating 0.9.0.4 with WordPress 2.7, the SECRET_KEY to which WordPress 2.7 key corresponds? I think I need that before using the integration plugin.
By the way, I tried the WordPress integration plugin for 0.9, and it does not work for me. After installing it on three different sites, nobody can login into WordPress. (I will ask this in WordPress Forums).
