I doubt it. People are just gonna join up there and not go anywhere else. I've been using forums too long to not know that.
Not so, we plan to have events for each site we promote that only members of said site can join into, thus members of our site wanting to access the potential contest/prizes will have to JOIN that site in order to play.
think of it as a tourney circuit within several sites. different site, same circuit, but different logins, potentially different house rules, and 1 hub site unifying them. (in this case our site would be the hub but since we are not focusing on assimilation of members, but rather, strengthening the global community, we will end off moving our members, or encouraging them to move from site to site/team site to team site playing in various forum contests/wars/events co sponsored by our site and the respective team site.)
your call though Tye.
