A couple of weeks ago the "Enterprise Library Contrib" project was published on CodePlex (www.codeplex.com/EntLibContrib). Meanwhile a couple of cool people joined the project, with intent to share and collaborate on the extensions they've made to EntLib.
Currently, 2 extensions have already been commited to the sourcecode; the "additional matchingrules" for PIAB and MySql support for DAAB.
If there is anything you would like to share, don't hessitate to sign up! as for now I am really curious as to how this works out.
