P411 is okay, as is ECCIE, I use both. However, in light of the heavy LE presence in Shreveport, and the fact that some hobbyists can't keep from rolling their accounts to said LE, I like to try to give a Security Question and Answer to the lady seeking the reference. Usually about something the client and I talked about during our session. To me, this better ensures that she is seeing the same gent that I did, not just the same Handle/phone#/name
I also make an effort to get to know the other ladies in the area, some of whom I now call friends. When I request a ref, I ask for some lil extra info or physical description.
As always, I am reference friendly and available to anyone who would like to share/learn screening tactics
Have fun and play safe!!
