join 1 of 2 specifc usergroups

[Crrrazzzy]

i run a few free online gaming tournaments and am looking for a usergroup load balancer

user joins tournament A and gets placed in either usergroup 301 or 302 depending on which has the lower members

user joins tournament B and gets placed in either usergroup 303 or 304 depending on which has the lower members

i have a working tournament registeration for http://www.bfewaw.com/roster.php and it works perfectly, however since upgrading to VB4 i have yet to find something to work with http://myinternetservices.com/tournaments/

i should also mention that they need to be placed into the secondary usergoup and not the primary

a way to make it work by executing an sql like this

UPDATE `test_testvb`.`user` SET `membergroupids` = '301' WHERE `user`.`userid` =1;
