John Sieber contacted me two weeks ago, he was trying to use ColdFISH as a Mango Blog Plugin and was having an issue with the Toolbar not showing up. Mango didn't like the way ColdFISH was generating the Toolbar, but after a pretty minor change to the formatter component we were in business!
John has posted the ColdFISH Plugin for Mango Blog project on RIAForge.
ColdFISH is now used by BlogCFC, Mango Blog, and CFLib.org. Who's next? :)
P.S. It's always great to see your code being used. It's even better when people volunteer to extend your work. Thanks John for making the Plugin!
