Actually, ATC is only an age limit of 16 (I found that out the hard way, but I've been 16 for quite sometime now, and I re-registered on my birthday). I haven't posted much at all lately on ATC, but it's still a great site if you want some opinions from people who actually are old enough to know that the top 25 musicals of all-time DEFINETLY don't include Rent, Wicked, Aida, etc. (though I do love Rent).
On ATC, they save as much space as possible by deleting anything considered a "poll" (any post asking for many different opinoins), and anything "OT" is not allowed. Also, because posts don't bump back to the top when a new response is added, most posts only last for about 3-4 days, with no one really reading anything after a day and a half. No avitars, no signitures (though some have some things they put at the end of every post). BWW is more user-friendly, but if you're looking for a real good discusion that likely won't bring up the phrase "Oh, my God, Wicked is soooooooooooooooooooooooooooooooooooooooooooooo awesome," than ATC is a good site. Don't LEAVE BWW, but definetly take a look over at ATC.
