I find it hard to change my av. I don't know why, but when I find one I like I usually keep it for quite a while. The one now is from the new doc and I loved the pic of Glenn so much I knew it had to be one. I don't know when I'll change it. Something will happen to make me. Could be a comment from someone or just a new picture. Who knows?!
The sigs are different. I'm not good at making them. This one's for the doc, but they aren't that important to me. If I knew more about it, and I know some of you have tried hard to teach us, maybe!
I do like having the choice though.
