I'm a member of a national organization here in Colombia, which is promoting a candidate for next presidential elections. This org has got Groups in several Departaments, and each Group has got several commitees. I'm suggesting them to use a mailing list to enhance communications among commitees, Groups and the whole org. We'd like mailing lists like yours, with a single addres for every list (like your @lists.sourceforge.com) and one list for each commitee (like your inskcape-devel, inkscape-user, inskcape-translator...).
I know your list is powered by Mailman, but I'm far from skilled at such. I need something free (we're lacking resources), easy and web based (I have no computer of mine, I work on Cyber-coffees).
Could you please help? I really appreciate your opinions.
