On Monday and Tuesday I set up a Frontier CMS at work for the project I'm working on. It went together pretty painlessly... I basically just followed the step by step directions in the mainResponder section. It's even searchable! I was impressed...

I wish the HTML it creates was more customizable (it's pretty odd to see something in Frontier that can only be customized by modifying a UserLand script), but for our needs, it should be okay!
