I bought the Cold Fusion MX Web Application Construction Kit earlier this week,  out of a sense of urgency to get going and learn this....already several contacts I have made are doing work in Cold Fusion.  Since I'm already in the Macromedia fan corner,  I might as well do it.

It all looks so familiar,  from having been an ASP developer.....the learning curve seems to be quite manageable,  and having an editor that will do code via a familiar WYSIWYG environment (Dreamweaver) makes it a candidate for even faster mastering.  Forta's book seems quite complete (1500 pages).  I hope to find some reputable training,  if not just start working my way through this book and the accompanying CD.
