It's still a weird rule. As soon as you join up, you can post on any other board. What's so special about off topic? (I suppose if I could actually see, then I would know.)
Things tend to get a little further sideways in Off Topics than they do out here. Things get said that don't represent the true nature of our beautiful souls.
Or something, mostly we try to see how much skin can be shown in the picture threads without it outright being nudity. It's all buggy whips and syphilis, you're not missing much.
