I had the plug-in installed originally, but I used my roommate as a tester (he's a programmer) and he cursed mightily the fact that the log in was redirected through the forum. I understand it would be nice for forum users to log in automatically, but then I don't expect forum goers to post in the comments and I don't want to put off the section I'm targeting who are used to WP and prolly don't want to have to register through the forum...if you get my drift?
