Re: integrating bbpress with wordpress
I would try the cookie sharing stuff in both bbPress config.php:
$bb->cookiedomain = '.lumanation.com';
$bb->cookiepath = '/';
And then maybe the cookie stuff that you can put in WordPress wp-config.php (can’t remember the format) if the first stuff just doesn’t work out straight away.
If the users are there it is because the integration is working, just the cookies are not sharing. Try that out and let me know.
