I might be the only one who would like the ability to be redirected to the forums after login. Our login sessions expire after a few days (might be a week), but once our session has expired, we are obviously required to log back in.
To me the reason I log in is the forum, so to me - it makes sense to be directed to the forums instead of our personal profile first and then having to navigate back to the forum. :)
Just a site usability thought and something that I was wanting to suggest for a while.
