Newsvine has seen fit to force me into the beta which limits me to 15 groups. I do not currently use Linux but I did when I added this group. While I like Linux I do not like it enough to devote one of my scarce groups to it.
Currently I am the only one with Admin rights in the group, who would like honor? It doesn't take much time at all to approve new members and delete off-topic seeds (and boot the occasional spammer or serial off-topic seeder).
I will stay in this group for a week, let me know before then if you would like Admin rights.
