I stopped playing SL a few years ago and now I really want to log back on to my old account because I was a well established avatar with a lot of inventory. I know my username, but I don't know my password or my email that I linked to that account. Is there any way I can get logged on to my old account? I really don't want to use this new account because I haven't played for so long and everything is completely different and I don't know how to do anything. Please help! Thanks!
