This is one thing programmers don't like to write - and i'm no exception :-)
But to say at least something: try it out for a while and decide whether you like it or not .. by the way: the contact "muc" means MulitUserConferece - there you can find all Conferences you've selected to be logged.
As the plugins are supposed to be - this plugin is published under GPLv2.
Currently it's only me (SmilingJ) who's working on Netlog. If there are any questions youst write to smilingj@smilingj.net.
