We just launched discussion forums on the ActiveRain Real Estate Network. These forums are accessable anywhere you are on the site via a link title "Forums" on the near the top of the screen. There are currently about 20 different discussion forums on various topics ranging from "Introductions" to "Search Engine Strategy" to "Feedback on ActiveRain"
If you have questions on pretty much anything real estate related, post it in the forums, and I'm sure someone around here will have an answer. No posts there yet, but given how active this community is, I'm sure there will be soon.
