Janusz: Thanks for the fast reply!
You have all this (perhaps without RSS feed and direct messaging) in the sympa mailserver recommended by me earlier.
At least RSS is essential for me, as it permits me to filter automatically with a rather fine granularity. (Yes, my preferences anre just *my* preferences.)
What most forums (at least those I know) are missing is a convenient way to selectively quote other postings, which negatively affects exchange of views.
I'm using YaBB. No problems with selective quotes there.
Thanks again, best wishes
