Hello,
Last week xirzon proposed to separate the chat traffic for the mediawiki software and the one for wikipedia servers. The idea was :
#mediawiki : mediawiki software development and support #wikitech : wikipedia specific issues and servers support
I personally find its a good idea. Users asking for support in #mediawiki often found their question flooded by wikipedia's servers administrators :o)
We could also get a bot that post cvs commit to #mediawiki since the traffic will be lowered (or maybe #mediawiki-cvs could feat this better).
