I learned about SR on the Dis - Restaurant Reviews. Sarah - SM from NC did hers and said how she got in an extra "free" dinner thanks to SR. I PM'd her and that's how I found out about SR.

I had NEVER scrolled to the bottom of the DisBoards until she told me about it and I had been addicted to the DisBoard site since August of 06 but didn't find SR until March of 07!

If someone does a dining review and thanks their SR gift cards that may help.
