Thanks, Julie! And we should probably add that there are many other places where the DH community gathers to share their experience and ask questions. Rather than point specifically to a set of specialist email lists (like TEI-L, etc.), I'll instead offer just a few other big gateways:
http://www.arts-humanities.net/
the CUNY Digital Humanities Resource Guide
http://www.hastac.org/
and, of course,
http://digitalhumanities.org/
and the searchable archives of the Humanist list.
We encourage everyone who responds to questions at DH Answers to point to the more specialized email lists and discussion fora where they are relevant and appropriate -- and also to refer people from those venues back here!
We're depending on the community not just to pitch in and answer questions here, but also to help map out the whole, helpful, international landscape of the digital humanities.
