OK this has happened to me twice now and I hope it's not being caused by something I'm doing that I just am not aware of. But like I said it's happend a couple times and the first time, I noticed that I had like 10 people on my buddy list when I really have only 3. I deleted all the extra names, but today I log on and there are like 20 people on my list now. What did I possibly click that I just don't know I did or what could be the cause of this?

Thanks.
