Nulavatar is a phpbb mod created buy Nuladion who has since retired from the community it was further advanced by ethalic (insydius) to further work with ADR. The problem is that it runs to many queries
"As for NulAvatar, Nuladion indirectly express his unmotivated to continue towards and development altogether only to return to his site to lock up the majority of it along with disallowing new registered users from joining. As for the ADR integration I had created awhile back on my same trademark site that I proved in my devfiles, I manage to get all what I was looking for only to realize the expense of the queries it generated, anywhere from 1000 to 9000, times that by the number of users actively changing and saving and you get a big mess." - Insydius
So maybe ajax is the solution.. I don't know but I know if I regain my players from previous years i'll have about 1200 active players thats allot of queries
