TinyOS contrib -- external projects that do not track with TinyOS releases -- are still on Sourceforge. The main tree is on Google Code. If you want your code to be in the main tree, then it would need to be sponsored by a working group (in this case, core). The benefit of being in the main tree is, well, it's in the main tree so everyone has the code by default. The drawback is that you have a much greater obligation to fix bugs promptly and for testing on releases.

If you want to be in the main tree, contact me off-list. I can bring it up with the core WG on a call soon, although it might not be for a little bit. Right now we're finally getting to testing 2.1.2.
