Congrats!
My own 10 year anniversary on sherdog is sometime within the next 5 weeks, but unfortunately I don't know the exact join date, because my original account has been banned for over 9 years now and cannot be searched. If you look at old threads in which I had posted in with that account, such as "I saw BJ Penn at the airport after UFC 63" my old account (Tbonetron) is in there, but it shows up as a "guest" or something, it won't show my exact join date or post count. But I know that it was August 2006 that I made it.
Edit: I wonder if Dragonlord or Cool Hand Luke can use their new "admin" powers to resurrect a long dead account.
