What is and isn't allowed in terms of before and after photos? I assume naked pictures aren't allowed but what about undies ones? I've noticed some people use black out boxes, but I'm not sure if that's because of the forum rules, or just personal preference.

I don't think we've ever established any rules, but we'd certainly recommend blackout boxes or plenty of clothing Our forum is read by far more people than actually post here, so there's a good chance that any revealing photos will end up somewhere you'd rather they not be.

Another rule of thumb, is keep is clean for the younger crowd. We have a few young ladies and gentlemen here looking for information.
