A couple of years back (wow, was it so long ago already?) while I was writing the book Extending Flash MX 2004 with Todd Yard, I registered the domain name, flashextensibility.com. I had a site up there for a while with info about the book, a forum, and a repository of extensions, not only from the book, but submitted by others as well.
As time went on though, I drifted away from the extensibility scene and the site got kind of stale. A few months back I decided to give it up and let someone else have it. Peter Elst stepped forward. He was the technical editor for the book, and knows the subject well, so I was really happy to hand it over to him.
After a short break, the site is now back on line with some nice extensions up. I plan to add a bunch myself. If you use the Flash IDE at all, you’re definitely going to find some good stuff that will speed up your workflow. Do yourself a favor and check it out:
