Hi,
Say I want to develop a site with some CMS embedded in it - e.g., a Wordpress blog and phpbb forum.
What's the most convenient way to unify the log-in and sign-up process for my site?
Letting users have a different registration process for each part of the site would probably scare any sane user away.
EDIT
I prefer generic solutions, not necessarily for the aforementioned CMSs.
