In my quest for a text editor/tool for Coldfusion cheaper the Dreamweaver CS4 and CF Builder I stumbled upon riaforge.org. There are hundreds of coldfusion apps that will save you time and energy developing your own.
For Example, My boss wanted me to build a project tracking tool so she can be more aware of what we are working on and when we complete it. She had a ton of requirements including communications tools (messages/emails/comments), user assignment, calendar components, edit/copy/delete tasks, calendar events, file upload/download, etc…
I got lucky and found this Project Tracker tool which is very similar to Basecamp from 27 signals. It has almost the same features with the exception of the whiteboard. http://projecttracker.riaforge.org/. After an hour of setup and a 30 minute demo of the features , I look like a genius.
BlogCFC looks like a neat tool to.
Worth a look out there if you need apps to support your customers or coworker.
