Sorry if this is the wrong forum to post, but I don't see an admin section. I've placed a (non-linked) banner in my sig line twice in the last 48 hours successfully. However, after about 24 hours it disappears from my sig in posts. When I check my "edit sig" in the CP, it shows up.

Am I doing something wrong? I thought the first was deleted by mods, but the second one is a mystery....
