MSBuild or Team Build Tasks in the Community

Just thought I would consolidate some resources after my searching for some extensions to MSBuild.  It looks like the internet and corporate community is very active.

Here is a list of a few sites of interest. The resources are listed in order of what I personally like first.  Note that the following links and organizations do not reflect my opinion or endorsement (nor Microsoft's) and is intended for informational purposes only.
