Mary replied the topic: How do I change my signature
I have just checked mine and I would be able to change it if I wanted to. You are definitely pushing "edit" after you get to your profile page aren't you? After that, there should be a menu appear with "avatar image" as a header. Are you not getting that?
Not every day is a good day, but there is good in every day.
