In an effort to provide a little bit more visibility into RubyForge sysadmin stuff, I've started a new RubyForge admins mailing list. I'll try to post admin changes/problems/etc here so's more experienced folks than I can comment on things. It'll probably be a pretty low-volume list since it's such a specific topic, but hopefully it'll make things more transparent.
Anyhow, feel free to join, comment, etc. Hopefully we can build up some general RubyForge tuning knowledge so that if I get hit by a truck things will continue without too much interruption :-)
