[Talk-us] Remap-a-tron level 2 complete! Suggestions for level 3?

Sun Sep 30 10:11:05 BST 2012

Hello,

         John makes some excellent points. The key to making this 
work would be to prioritize it. Otherwise, it's a neverending Remap-a-Tron.
         I don't have any strong feelings about how that should be 
done. I'm sure someone will come up with an excellent way to do that.

Charlotte.
