Hi folks,
I sold my N900 6 months ago and after a brief foray back in droid land I'm back with an N9. I'm liking it so far but I'm struggling with getting up to speed. There FAQ information on TMO on Meego seems a bit spotty. Is there a goto place to get started? Looking for repo info (which ones to use, how to add), how to get proper access to my device (term, ssh etc).

Any help much appreciated.

Enable developer mode in security>settings, that will get you terminal. If you want more hackability, there are custom kernels on this forum and there is always open mode. As far as repos, try warehouse, the N9 client for openrepos, and I am pretty sure coderus has one with some helpful stuff on it. I mostly install stuff from .deb files though.
I would also recommend fasterN9, its a big help, and if you dislike the standard meego styling like me there are a few themes in themes section of the forum

Welcome to N9land.
