Actually most providers don't really need a heads up about a review, but if it's a positive review I can't see any harm in dropping her a line saying something like "I really enjoyed our time together and I wrote you a positive review"  

BTW, Yoko is great, I saw her maybe ten years ago, and then again about a year ago. One thing you can say about Asian women is that they certainly hold their age well.

So, I put them on my favorites list and check that daily, and if they get a new review, I email them to let them know, which they appreciate

That is, to providers who are members here.  

For now, though, I can usually tell I have a new review by the sudden uptick in 2am texts and dumbass emails.  

 
If you're going to tell her you wrote a review, it would also be a nice touch if you had told her prior to submitting it, in my opinion.  Of course, you are under no obligation to do so, I just think it's courteous.
