Setting up approvals help

Hi List!

I want to evaluate approvals, because we want to use RT to approve request.

I searched for some docs, but I didn’t found anything, I thouth the best place whould be the WIKI, but…

Anyway I whould like to know:

  1. Where do I insert the settings for approvals?
  2. For which conditions do I have to set up my scrip?
  3. How do I transform a ticket in an approval request?
  4. How is the notification handled?

Thanks for any response.
