Yah, it was always disabled, except for the last week. I think it's better that way, so people don't PM a solution to someone's post, and then it doesn't get answered in the forum.
We made the profiles and memberlist inaccessible if you aren't logged in, so google or other indexers/bots won't be able to harvest emails from the forums. So its safer to list your email address in your profile than it was before.
