If I send a PM to someone, is it sure is going to have a email confirmation that he got a PM or we can disable this fonction. I just want to know if the person I PMed just don't want to answer me ( because he is logged off for a long time now) or there is a possibility i didn't know about my PM.

thank's for the information

At the bottom of the text area when you write a PM, check this box: "Flag:          Check this to send a message to you once the user has read the message."

si tu va dans tes preferences, tu peux en effet enlever "E-mail me when I receive new Private Messages"

(thank god)
