Connie,
There are some here who are quite adept at it and it works out well for them. I, on the other hand, went to change my profile a few months back and was off here for more than a week. I would like to change my profile pic (the one of Harry is my favorite and I'm okay with it, but I have a lot of really nice ones of him that I'd like to get on here) -- I'm worried that if I try to change anything that I'll have a problem again, so I just leave it as is. Good luck with it and if you do manage to do it easily, let me know
