CaliforniaPoppy, that AVRT choice you have made will definitely generate some conversation when you post. I think the idea is fascinating and elegant because it is so simple.
Posting on an old thread is not a bad idea at all. Even if some of the original posters have moved on with the business of life (just like AVRT suggests will happen), there will be other folks that might be seeing that post for the first time. If it is of interest to you, it will be useful to others too.
