well ya when when saphiraforums did it it had some very minor problems but they werent that bad but for a much larger comunity it may be a problem. some advantages are: friends and foes, more moderator powers, notifying if some one has posted after you started your post(my favorite), subscribing and bookmarking topics, usergroups (thats a phpbb2 thing but this forum doesnt have them.), more color options and makes it easier to use, saving posts that you havent finished writing yet, bumping topics (even though its not going to happen here) and more. heres a link to the site im talking about.see if you see anything different http://www.saphiraforums.com/en/index.php
