I would assume the recent influx of members is coming from Watergardens Magazine. Another thought is that Spring is just around the corner and has arrived for some of us. People start participating again on mass this time of year from my experience.
Oh, don't forget, we still have several hundred members who signed up on the old board that have not signed up here yet so our membership numbers are much closer to 900. I honestly expect most of the previous members to filter back and sign up once again.
Cheers,
