I installed Conversant on my work dual G4/450 running OS X 10.1.4. I updated all after the install but before going to any sites, then quit and restarted Radio. No problems to report. New site creation all works fine.
The only oddity is that after creating a site I receive a message telling me what the e-mail address of the site is, and the sender is seth. Must be some setting somewhere I need to tweak.
