Oakville (Ontario, Canada) Chamber of Commerce. Uses almost exclusively CJay Content, with a bit of WFSection, AgendaX, and ContactX mixed in. Gotta love the WYSIWYG editors (that is, if you're not on a MAC like me ;).
These are my first Xoops sites past simple upload and tweak. I loved using Xoops; there were times when I found it rough around the edges, but I got through with the help of community members. I'm really excited to see all the development going on right now; Dev team, Theme-people, you're all great!
