I answered "yes" but ... thought I should point out, we kind of do already have a club.
But I'm assuming you mean formalizing the group, making more regular meetings (we have regular meetings at irregular intervals), and, perhaps MAC registry, etc., and so on.
Currently the focus of the group entails group orders, sharing of knowledge, trading of frags and equipment, etc., and generally speaking this forum here is our focal point. To take it "to the next level" (so to speak), we sort of need to define what we want that next level to be. If we are talking about bringing in guest speakers from out of town (which has been sort of one of my eventual, but long-term goals), be prepared that this sort of thing costs money. Are we ready to start funding our efforts with a membership drive (and potentially other means as well)?
At the last meeting we had some 30, possibly 40 people (just by my guess). If everyone ponied up $20, that's $600 to $800, which is, I don't know but I'm guessing, halfway (or more?) of purchasing an airline ticket. Then we could truly consider maybe bringing in someone like Calfo, or Borneman, or Toonen or Delbeek.
But the flip side is, if you get 30 or 40 people with buy-in, you decide to go ahead, but then suddenly only 10 people show up for the meeting. Who covers the shortfall? As a society we will need to be prepared for this sort of thing.
Truthfully, I'm not certain we're really ready to bring in speakers yet. So that scenario is a long way's off, in my view. But we could make it our goal to still formalize, and see what kind of membership we could organize.
Basically, the thought I want to leave you with, is this. Wanting to start a club is pretty easy to do. But are you willing to pay for a club? That's the real question I think we all need to look at. And time. Are we ready to make a time commitment as well?
Obviously, a club that takes your money needs accountability; and that means registration (I think with the province, or maybe the city .. I don't know .. as a non-profit society), plus a executive council .... Positions such as president, vice-president, and treasurer, and event coordinator; would be my guess for the executive positions. At least for a start. Plus an agreement for a date that an annual general meeting can be held for elections.
Plus, I think we would want to arrange for an affiliation, at least a loose one, with the Calgary Aquarium Society. We're not trying to compete with them, but if we don't get buy-in, we could be perceived as such.
See? This could be a lot of work. Are we ready for this?
I think I am. I'll buy into the process, because I believe that we are indeed approaching the point where we could make this fly.
But be warned, we'd have a lot of work ahead of us.
