I don't look at TER to see whose available and If I haven't seen an ad in awhile on another site I will just shoot her a text or call and ask(depending on her preference) if she is available. The ladies that get back to me whether available or not get more credibility in my eyes. As opposed to the ones who do not respond. Hope that helps.

No, but it does add some credibility.  

send her an e-mail and ask if she's available on -time- -date- and, if not, what -time- -date- will she be available.... and I don't read the local board ads, I just look at the pictures... unlike when I was a puppy and bought Playboy for the articles, not the pictures (and if you believe that, I have some ocean front property in Yuma I want you to look at

No, I also check other boards.  Lady's do travel and not all have calenders.  It/they also can indicate that they are available say on an off day and looking for company. I hope this helps
