First REIA? What will I need? Etiquette?

[Justen Ashcraft]

So, I've been a real estate investor for a few years now (buy and hold). I'm somewhat of an introvert. I've also been receiving meeting information from the Atlanta REIA for about 2 years, and always read the email but never attend the meet-up.

I'm thinking about going this Monday and paying the $20 at the door. My question is, what is the etiquette? What should I wear? Being a natural listener and shy person, I just want to "melt" into the meeting. Anything would make me feel more confident, any comments are welcome. Thanks.
