Being so new to the aquarium "community" I have no idea what MACNA or MASNA even mean, but if recent meeting attendance is any clue WMAS has pleanty of people to support a large convention. If those of you in authority think it's a good idea then let's do it. I do think it would be a good idea for those in charge of planning such an undertaking attend MACNA or MASNA and have great communications with those people in charge of attended and previous conventions.
Just my 2 cents. (I'd be happy to help)
