I have a co-worker who is looking to use the site try to get a rental for their upcoming trip they would like to do in December. I let her know she needs 10 posts to unlock PM and she will need that to talk to anyone about getting their rental. After they reply to 3 threads the reply link has gone away. She actually created a new account to see if perhaps it was messed up but again after three replies the Quote and Reply links vanish. Is there some sort of throttling for new users with this?
