I sent out a request recently asking for suggestions for the upcoming term, and this was the response:
The drop-in fees from the spring and summer terms will be split between the two.
To help raise moolah for these great organizations please let me know when you'll be absent, as you know, so I can advertise a drop-in spot for that date. And also feel free to share drop-in dates with any folks in your life you think might be interested in some yoga in a pwyc capacity. There are 2 spots available April 15 & 22.
