coldfusion resources
The best resource for learning ColdFusion is other CFers. ColdFusion has an active and helpful developer community. Most other developers remember what it was like to be just starting out with ColdFusion and are usually more than happy to help if you get stuck.
user groups
One great way to meet other ColdFusion developers and learn more about ColdFusion is through the ColdFusion User Group (CFUG) community. Many large (and not so large) cities have active User Groups that come together on a regular basis to meet face to face and discuss ColdFusion and related technologies.
Adobe maintains a list of User Groups. Have a look and see if there is one near you.
lists , forums and web sites
There are several mailing lists and forums where you can post a question you have or a problem you have encountered and the collective ColdFusion community will help you solve it. These lists and forums are also a great place to just troll, looking for ideas and inspiration.
House Of Fusion - The grand-daddy of them all
cfAussie - A very active mailing list
MXNA - Macromedia Blog Aggregator
