FAQ:What is the prefered method for contacting the MakeHuman crew?
If you have questions, the forums are the default choice. ALL SUPPORT REQUESTS SHOULD GO VIA THE FORUMS. We have had to stop posting our email addresses because of the huge load of incoming support requests, so please don't try to contact us directly. This includes facebook: chances are we won't even answer facebook direct messages.
Bug reports should go to http://bugtracker.makehumancommunity.org.
If you want to chat directly with someone from the MakeHuman crew, there is an IRC channel, see FAQ:Is there an IRC channel?, but it is only infrequently visited by someone from the dev team.
And oh, before trying to contact anyone at all, please read all relevant parts of http://www.makehumancommunity.org/wiki/FAQ:Index
