Mailing lists are cheap...
...but I still didn't think I'd bother with one for sshuttle, which was just intended to be a weekend toy project. Seems people are actually using it, though, and it's picked up quite a few github followers already. (62 followers isn't that much, but the thing is only 10 days old.)
So okay, here you go: the sshuttle mailing list.
By the way, it seems to not be common knowledge that you can subscribe to googlegroups mailing lists without having a Google account or ever using their web interface. The secret is to send an email to "email@example.com", where groupname is the name of the group, in this case, sshuttle. Note that plus sign. It's not a minus sign.
