Bienvenue Marc, it's certainly the proper forum you're on. Since you read it for long there's almost nothing I can tell you what you didn't find out yourself. When I started reading it, I did learn a lot from experts like Karl Schneider or Valentin Albillo (to name just two). I can only recommend their contributions - probably you know them already. Enjoy!
