If you are associated with a Gym Pays gym on CrossFit btwb your individual subscription is covered by the gym. If you are switching to a gym with a Member Pays subscription, you'll be prompted to start an individual paying subscription. 

To switch gyms and start an individual subscription, complete the following steps:  

Login to your account on the full site and head to the Edit Profile link from the drop-down menu.

Select "Change your gym association".

Switch over to our Main Site gym (and enter "Varied not Random", our public Member Pays gym) or a gym of your choosing. 

Once you've switched to the Varied not Random gym, and assuming the gym is a Member Pays gym, you'll be prompted to start an individual subscription (monthly or yearly).
