Rigify: Where do I usually post a feature request? (or get dev-related assistance?)

Hi.

I’d like to either request a rigify feature (new skeleton type) or try to implement and submit it myself…

The problem is I’m having difficulty locating rigify development repository. Could’ve sworn it was on github, but I’m not finding it right now.

Can someone point me in the right direction? I’d like to know either where is the right place to request a feature or where the repository is.

It’s under pitchipoy:
