These are in the forum rules, but I will repeat them here as well.

+ Only post one gallery.
+ Edit the first post of your gallery please, don't post your graphics in subsequent posts - it looks messy that way. You may post saying you updated it.
+ Double posting is allowed to say that you've updated your gallery, but only every 2 days. If you update it more frequently than that, just post in the Pimp my Gallery game if you want it to be posted in by someone else.

If you have any questions about your gallery, please PM a staff member.
