Dav Glass (@davglass) is well known to the YUI community as the creator of the YUI Rich Text Editor, Layout Manager, Resize Utility, ImageCropper, and much more. His trove of YUI examples has helped thousands of developers fine tune their own YUI implementations.

Dav’s focus lately has been on YUILibrary.com, our community platform. YUILibrary.com includes our project tracking, bug repositories, and forums (documentation and examples are still hosted by our friends at the Yahoo! Developer Network). Last week, we debuted another facet of YUILibrary.com: the YUI 3 Gallery. Dav covers a wide range of developer/community issues in his YUICONF 2009 session, “Contributing to YUI,” charting the progress we’ve made in the past year opening the project up to contributions and in making YUI 3 as extensible as possible.
