Yeah I have been wondering this also. I don't think she's changed her account from offering services to seeking (a way to appear hidden but still have email access), as an email I have received from her in the past is now no longer showing the actual text, just the message saying the member is no longer active.
So that leads me to believe she has actually deactivated her account for now... I was hoping to book her as well, as she stated on her profile her next dates were going up on the 20th. So we'll see then I guess!
