what"s the meaning of "regions" in an online series?
in a live tournament, a region (Irish, English, etc.) means that"s where the tournament is held, and that makes sense.
in an online series, since everybody can join in, a "region" (Irish, European, Japanese, etc.) really has no meaning. you should either drop the regional monikers and use something else instead (like the month or the season) or only limit users from a certain region to join.
