Mike, the ONLY thing I can think of is you weren't on the team for a while. There are other members that have switched teams and the points do not move from one team to another. I know you joined Team UBBDev... and I do not know how your name was removed from the list but those other points went somewhere else.
The thing to remember is... those points are still helping a good cause and now your points are being added to the team points here.
Thanks for helping.
