I think Mike's idea is a good one. Hold a meeting for anyone who has interest in helping out with the club's meeting planning, setup, take down, organization, etc.
Some ideas for meetings:
1) DIY workshop on acrylic
2) Another talk about fish and their function/impact in the reef aquarium (especially gobies, tangs, blennies, and angels).
3) A night dedicated to soft corals (maybe a fragging meeting where people bring their softies to frag and trade)
4) a night dedicated to LPS and their care
5) SPS night
6) a speaker to talk about small/nano tank setups (anything less than 55 gallons)
Just some thoughts
