I don't know what's happening. I only wanted to change my avatar and now I can't get another one. Also, I've tried changing my signature too but it still leaves the old signature that is there so I can't change that too!
What's going on!? Can you change it back to the way it was please!?
No, the system allows .jpg, .png and .gif formats, all that matters is that the avatars don't go beyond 5MB in size. I always uploaded them as .png, it's the system that converts them into .jpeg.
