I posted a few seconds (lol) ago on "Avatar Idea (page 9 for current idea)" and my post didn't appear atthe end, but behind someone who posted two days before me. Explain whether this is a strange glitch or some type of thing installed I didn't know about.
That happened to me before, and it's pretty rare. Don't worry about it unless your post seems strange in that spot, if it is them tell a mod to delete it and repost it.
