Rings is right. If you see the smaller version of your avatar it just means that you have posted in that thread. When you see this thread you will see the smaller version on top of the avatar of the poster that started this thread. Just lets you know that you have already posted in the thread..
Here's the screen shot. The second avatar appeared as soon as I posted the thread. If its a good thing--great. Just wasn't sure if I screwed up.
WELL..... I just spent 20 mins trying to insert the screen shot and all I could get was the damn thing asking for a URL. Good thing I've still got 5 months before I can get a new phone or this one would be in pieces!!!!!!!!!
The screenshot shows what Rings was saying.
