Awilda, your tank would actually be a good selection for this purpose. Don't be too critical of yourself.
taat2d, you would be defying the purpose of such events. The best way for me to learn was to go and look at systems and figure out what techniques were best suited for what I am able to do. If a bunch of experienced guys go to your house, you'll get a million solutions on how to make your tank better, none of which suit your husbandry techniques. You should focus more on possibly attending a meeting or 2. Neither me or Randy is more than 15 minutes from the bridge. You've also got a good reefer or 2 out there who would also be capable of hosting events.
It doesn't require a full blown SPS tank to host. You also don't have to be the most experienced/least experienced to attend.
Also, the idea isn't to sharpshoot a system. It is for the host to show what has worked for them, why and how.
