In version 0.6.2 of b2, the admin can set a AutoBR flag. This feature is gone in WordPress 0.7. I really hate AutoBR because it forces me to format the message myself. If I have an URL in my post, it's impossible to format things nicely myself. Please put AutoBR back!
Well, at least don't remove it permanently! Right now, at least I can just use "$br=0" in the 2nd parameter to the wpautop() function in "b2include/b2functions.php" and disable AutoBR when viewing my posts.
