I think, this has been the quickest and so far trouble free CMS I've ever tried.
I am yet to read the manual, but I have a quick question for those with more experience with Silverstripe.
Is it simple to skin it? my main concern is to be able to mantain the look of my existing sites.
I've found that creating templates for SilverStripe is easy. Start with the [url=http://doc.silverstripe.com/doku.php?id=tutorials]tutorials[/url], then if you have any questions, ask here or in [url=http://www.silverstripe.com/irc/]IRC[/url].
