Time sensitive reviewing.

I have one more question, then I think I'm done. What is the time sensitivity on reviewing? I have a review I would like to make for a provider from about 6 weeks ago. Is that too long ago? At what point is the cutoff for being able to post a review?
To get PA credit for a review the cut off time limit is 30 days but you can post an older review to share the information even if you don't get credit for it.
Excellent. I have some pretty decent credit right now, but still would like to get a couple up from Feb-March, before I was posting here. Thanks!
