So as I've said before - I sometimes have trouble finding things on Adobe.com. If you're like me, hopefully the following two links will help:
Installing ColdFusion Builder (Online)
Installing ColdFusion Builder (PDF)
Using ColdFusion Builder (Online)
Using ColdFusion Builder (PDF)
And finally, I want to share a graphic Adam Lehman posted earlier. It's a competitive brief of ColdFusion Builder, Dreaweaver, HomeSite+, and CFEclipse. Click the shrunken image to enlarge.
3 links? Think I was a bit off on that. :)
Edit at 3:49PM: And yet another link - the CFBuilder Forums may be found here: http://forums.adobe.com/community/coldfusion/coldfusionbuilder
