Thanks a lot for the answer all of that are good news, both the possibility to answer directly from the mail and that messages will be moderated before posting (that I had already discovered after validating the first message :) . Concerning the reply by mail, in the daily summary I've chosen to receive, the first big message I have is
Do not reply to this email. To view and reply to a topic, click the subject.
So if the option to reply the mail is available, it should be good to improve the message in order to avoid confusions.
