I usually keep an eye out on the ladies schedule. Especially if they are not a regular. Some girls go to school for a couple of months, and then come to the brothels during spring break, summer break, winter break, etc. The way I was told they are only supposed to communicate with you through the boards or their brothel email, so management can keep tabs on the girls. However these days lets be honest, there is twitter communication going on. If twitter is an option, and I don't hear back within 2 weeks I will assume it's a no go.
