if i was you i would do my best to attend the meeting on sunday and get to know some of the folks in person. everyone is very friendly, and you will have a ton of people to ask questions about fragging. the best part about this meeting is that it is being hosted at a saltwater shop, so fellow members will be able to show you exactly what glue to use, we will be able to show you exacly where on a coral to cut to propigate it, etc.
you can look at some of the other stuff coming in, and ask around when you see something you might like. if you have access to a digital camera and can get some photos of your stuff, people will be able to "shop" in your tank and you will be able to set up future trades for stuff from their tanks.
best of all, you will not find prices cheaper than woody's and the quality is top notch, so if you come prepared with 20 or 30 dollars, even if you can not find people with frags for sale, you will be able to get some nice stuff from him so you will not go home empty handed.
from my experience at the last 4 of these however, there is always loose stuff floating around at the end of the meeting, and those who are just starting out or who are moving towards corals for the first time are usually able to get a piece or two to get them started.
hope that helped a bit, i can answer a lot of your questions if you wanna come stand by the grill on sunday, otherwise you can pick the brain of everyone else.
never fear, there will always be someone looking for exactly what you have to trade, it is just a matter of getting something from them that you can put into your tank.
look forward to seeing you there hopefully!
