Hello,
2009/3/4 Sergey Chernyshev sergey.chernyshev@gmail.com:
You don't have to commit your extension to MW repository - there is no problem if you host it externally. I used Google Code hosting for a long while.
Really only extensions hosted in Wikimedia Subversion can be localised on Translatewiki.net, so it makes sense for most open extensions to be hosted here - there is also much less of an overhead in terms of project management.
