A lot of our discussion happens on IRC in #metasploit on Freenode. Please be patient and hang around for a while – not everyone is awake at the same time as you. =)
The Metasploit development mailing list used to be hosted on SourceForge, but is now on Google Groups. Metasploit Hackers is dead, long live Metasploit Hackers. (Or mailto:Metasploit Hackers).
The old list is archived on seclists.org.
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to firstname.lastname@example.org which goes to all the current committers. If the incident involves a committer, you may report directly to email@example.com or firstname.lastname@example.org.
