Hi all,
I'm not going to be shutting down this list, but if you have questions or awnsers and want to participate in working with and helping each other to solve problems then I'd encourage you to give the new site a try.
The problem with the google group / mailing list is that things are asked, answered, and forgotten. Posts aren't easily searchable in the future and then don't help people to answer their questions. The google group and mailing list is still better for conversations, so that's why it's not going away.
best,
Tim
