My post is three weeks old. I don't remember if your account was one of them but a few accounts were close to the 2,100 line so you might have earned some more in the last three weeks and just recently entered the 2,100 or more POB club. Anyway, congratulations on the stake.
It is alright, just wondering. I have had that since a couple of years ago.
