I made a list of questions I had and used the search function first prior to posting and I found the answers to every question plus a whole lot of additional great information.
Based on the large number of duplicate questions posted I am going to guess that people don't know how to use it or think it is too cumbersome to go through old posts. There is a button on the upper right that allows you to sort by either relevance or date so you can get the info you want quickly.
How to get from CDG to where ever you want to go - there's a multitude of replies.
Versailles - it's all there.
Airport shuttles - oy vey
Restaurants, museums, markets, etc. - so much from the easy search function
The only downside is spelling - you and the other posters need to get it right. But that is easy to navigate.
Thanks to all for sharing so much great information.
