Nice LGPL HTML Content Editor (as an ASP.NET server control)
...Been working on a custom content management system for a client lately, started using some of the basic contenteditable capabilities in IE. Kinda wanted to go the route of a Rich Text Box but #1 did not want to waste the money, #2 did not want to waste the time. Then today I stumble across a sweet little open source clone at http://www.fredck.com/fckeditor/
Hey, if someone else will do it for me; more power to 'em!
