Since we're "thinking out loud" - How about broadening the scope to include a much larger geographical area. i.e.
Michigan Marine Aquarists Association
Great Lakes Marine Aquarists Association
MidWest Marine Aquarists Association
Or some variation thereupon.
Here are a few considerations,
I think there may be a void that could be filled - There are other great organizations, such as MASM (to which I belong) however, much of their content focuses on breeding and sustainability. Both of which are hugely important, but perhaps a bit too focused for the masses.
Larger potential membership means larger potential revenue, driving more benefit to members. The ability to provide resources such as PAR meters, suction cups, or other specialty resources on loan or at minimal cost would be a significant benefit and draw.
We could also pursue MASNA affiliation (if desired.)
Engage Corporate/vendor sponsors - larger membership would attract more interest/support (Jim - huge ground floor opportunity here )
Offer special recognition as a founding or charter member to those that help build the organization and or provide seed/start-up funds.
One of the drawbacks of a larger geographical area, is that distance makes it harder for many attend/participate. One solution is using Webinar technology. I have the ability to host live video/audio webinars for up 1000 simultaneous users. These types of technology, including streaming web cams, can be used to help include members in both educational and social functions.
Thoughts? - Sorry if this is waaay off track, and feel free to ignore - it's always been my nature to "upscale" things.
