can I include the reply in the notification? - no answer yet

I just want to know if there is a way for the system to include the text of the reply in the notiffication e-mail. (like with newsletters)

I am not sure you can send a welcome email, but you can send a Welcome PM.

ACP - General - Configuration - Private Messages and Email.
At the bottom of the Private Messages header, you will see Allow Welcome Private Message, click to enable it and below that you can write out what you want the message to say and who the sender will be.

I did not mean a welcome email/pm. I meant that when you have notifications activated, you get an email saying that there is a new reply, and it gives you a link, to read the message.
What I meant was, if it is possible to include the TEXT of the reply itself....

bumping it up

no that isnt possible at the moment.
