Jojo, There is some strong resistance to converting to a forum.. I think most of the key players are happy with this (well run!) mailing list format.
I would recommend finding an existing web site that focuses on LENR and getting involved there. You can post here and link to the site you choose. Most forum software has Blog support built in, so any builder could start their own project page and save images and documents... I have two sites I built that anyone can request full admin rights to and modify all they want.. http://ecatplanet.net (VBulletin) and http://ecatbuilder.net (Wordpress) But they haven't gotten much traffic and I don't have the time to properly maintain them.. There are also other LENR replication sites: http://www.buildecat.com http://www.alienscientist.com/ and http://www.fusioncatalyst.org/ - Brad
