I started a thread asking about French-themed forums, Facebook-type sites etc, but now can not find it, even with the search engine. Was my thread knocked on the head?
I found it by clicking your username and searching for all posts - French forums or Facebook type site - Miscellaneous and Personal Stuff I Must Share - Straight Dope Message Board
Oh, my google fu is broken. Will look into it. Merci!
