The Ledger project now has a new mailing list, hosted at Google Groups. This was requested by several users who were not happy with the current web forums being used. Note that you do not have to join the group just to post a question. I’ll be keeping the web forums up for another year or so, but will start discouraging their use.
Also, you can find a few of us on IRC at irc.freenode.net, on the channel #ledger. My own nick is “johnw”. Come say hello!
