Does anyone have any recent knowledge of Jenaveve Jolie?  

and yet TLC still has her listed, with many others who are not available.

A lot of the dropouts do climb back in...multiple times.

I saw JJ 10 times over the years and she was great. We still occasionally email each other but she's definitely retired and has moved on to her next chapter in life. She's happy and healthy and I seriously doubt will be coming back to be Jenaveve Jolie.

Just because someone is not generally available doesn't mean they won't come out to play if the circumstances (and money) are right.  I know a few "retired" ladies that will still come out to play for regulars, or high rollers.  And some of the listed ladies on TLC who are "retired" are personal friends of Adonia and, again, if the circumstances are right will come out to play.

She was recently added on my platinum provider,

I don't see her ANYWHERE on the website. I also do not recall her name being on any of the recent email announcements from MPP. Where did you get that she was booking through them?
