IRC channel which is dedicated for Manulix talk is #manulix @ freenode. I can't be on IRC 24/7, but it should be the first place to try to reach Manulix team.
The second place to ask some question is project forums.
The main developer of Manulix (and Manulionix) is me, Douglas Mencken. My e-mail address is:
