These are the added on rules for the gym, the official rule still apply.
1. Keep Gym names appropriate, don't post anything inappropriate as a name.
2. To keep things simpler, the name format should be as follows: (Your chosen name) Gym - Gym Type - (Status, Opened, closed, or on a hiatus)
3. TitanniumMan141 has a perfect example of a good gym layout, you do not have put it exactly like this, but it should be at least be relatively close to having the same setup(It can be in a different order, just include the needed information)
