... Obviously as many people as we could gather within our members, but I doubt that is going to happen. Toys 'R' Us has an afilliation with Hasbro on Beyblade tournaments, so they would probably not allow our events to be hosted within their doors. MorningMess even clearly got refused, and in the end an official tournament is happening at that Toys 'R' Us.
In any case, this is very vague. Just try gathering interest in your own area for a start, and we will see afterwards.
