Okay, I'm not trying to be obnoxious here. But if you read the TOS and other, what do you call 'em, stickies? in the Announcements section, you'll find this information right there, in the third entry. I know it's a lot of reading, but at least it's all in one place. (It might not have always been that way, but it sure is now.) Reading those announcement threads is part of your responsibility as a member and can save you a lot of time and trouble later.
