I have posted a review for a provider about 4 months ago and saw her again today.  Should I post another review or not.  Her amazing skills and personality have not changed.

You won't get any VIP days for it, and it will just replace your original one on her profile.  It will show up on your profile as approved, an the original one will be disapproved.   if it's not significantly new, it may not even get approved anyway.  My advice, wait till you see a new provider, then write a review.

write a new review. As swim said, it will just replace your old review (if it gets approved at all) You get no credit. The lady still has the same number or reviews,etc. The only reason to write a new review is if her looks or performance changed (good or bad) from your last experience, or if it was a completely different kid of date. For example your first date was for one hour, and your latest date was an overnighter. Otherwise just leave the original.

Maybe one other reason I just thought of: If the lady does not have any recent or current reviews and wants one.
But generally no changes in looks, performance or date type, does not warrant a new review.
