Learncf.com is a new web site that aims to help people learn ColdFusion via tutorials with running demos. Everything must run on CF 8 and the tutorials, so far, mostly show off the new features of CF 8 like cfwindow, cfpresentation and .Net features.
And if you submit a tutorial before the end of the year you have a chance of winning a copy of CF 8.
I've contributed two tutorials so far on auto-saving a form and showing off some of the new file functions. I find that once I write a tutorial with explanations then I truly understand a topic. Other contributors include Ben Forta, Sean Corfield and many others. To submit a tutorial go here. The site is the brainchild of Dale Fraser, an Australian ColdFusion developer.
