Hey Ed, my take on this - the type of meeting you want to have will dictate what you will do....if you want it to be a get-together of people - getting together to socialize and meet each other, then frag swap is a good idea, maybe have a topic about coral placement or something to go along with the swap. If you want it to be more than a get-together...then maybe have a topic on easy DIY projects (fluidized reactors, sumps, etc) You wouldn't necessarily have to build them there, but talk about how they were done. This was just an example...you could organize any type of speaker/organized topic.
