Hi Paf,
I didn't know that you speak a so good English!
I am very happy that you finally came in this forum.
You know, we are many to be on both forum. At least tens.
So we already know what each community is missing.
On this site there is the forum "Citrus swap (Buy / Sell / Trade)" and on the french site there is "Les échanges - Recherches".
A cultural difference is to notice (and accept), for French people (and most of Europeans) it is impolite to ask for money even for envelope and stamps (unless you're a professional indeed). In America it is very common and nobody would be offended for it. It is good to know.
Beside cultural differences, on both forum you will find good friends and valuable knowledge.
Welcome!
Sylvain.
