So we've all been there. You get to a site, you like the idea, you are looking through the information and then you find the deal breaker. Whether it be members or a rule or something else you find that thing and you go "nope, that's a deal breaker" and hit the x and move on. What are your deal breaker items.   Finding the rules and seeing that the admin was unnecessarily rude or overbearing.. that's a deal breaker.
