How to challenge a gym

If you want to challenge a gym you request it in their topic,ex. if i wanted to challenged the fire gym i would go to gyms and look for the fire gym and post my request. Challengers must register their team in Team Regristration and cannot modify it so chose carefully. You must go by the gym rules , Gym leaders can put conditions such as clauses. Gym leaders can post how often you can challenge them and the gym trainers go by the same rules. When you defeat a gym leader YOU AND THE GYM LEADER OR TRAINER, must send an admin a PM saying you beat it so i can modify your registration so it says you have obtained that certain badge. Gym leaders will make a new topic introducing their Gym and its rules , the leader will say if it has a current trainer and both its teams , Gym leaders may change their teams but must change it on their topic. Trainers cannot do this.
