Here's the announcement from Bob, the person who runs this program:

We will start the Spring session of open gyms on Monday March 6 and Wednesday March 8. This is for advanced players only. Each night will run for 9 night from 9 to 10:30 pm. The cost is $90 for each 9 week session. ***Because of limited class size, you MUST sign up for either of the nights (or both of the nights for $180). I will have the registration forms the first couple of nights.
