So after looking at the google site, I found this: http://code.google.com/p/openmeetings/wiki/UbuntuLucidLTS
which links to a couple of other pages describing installation on 10,.04 LTS here: http://openstudio.info/component/content/article/60 However, it still doesn't provide any package requirements options for the initial installation. I thought I saw a thread on the mailing list archive that spoke of a block diagram. This would be helpful. During the initial installation, what packages are "required" and what is "optional"? Thanks! Allen
