I'm gonna feel like a tool for asking this, but my signature is a gif and someone told me it was over 40 kb, the maximum size of signatures. I wanted to go to the horse's mouth to see, instead of getting reprimanded later on. (I've already had it for three days, but I don't know if the mods just aren't noticing it or what.) I've also seen some people who aren't Supporters using gifs as avatars. What's going on with that?
