I use Grawlix CMS for my website which I started back in June. I think it's extremely helpful and a great starting point for website design.
I have since starting the website implemented my own codes for the page updates on the front page and the archive system, so I'm glad it lets you do your own editing in the html.
The problem I've come across is that the advertising section in the admin panel just doesn't work for me for whatever reason. I was able to manually put projectwonderful ad box codes in the home html, so it's not that big a hassle now.
