The BZFlag FunMatch Challenge returns on March 31st, 2018 for a triples event on HiX. Registration is now open at http://challenge.leaguesunited.org

The rating method has changed from what it was in the past. Rather than using 1vs1 League ratings, the site will now
pull in your personal ELO rating from the LeaguesUnited site instead (winter season). As before, your team rating will
be the average of the individual ratings of all your members. The more official matches are played before the event, the more accurate the team ratings will be for the event, so I encourage everyone to play as many of them as possible between now and then.

A higher rating will earn your team an easier path on the ladder, but tied matches will go to the lower-ranked team
during the tournament. Please keep this in mind, because this has occurred in the past and not everyone was aware of this rule

See you there!
