Working artists, folks who want to be working artists, techniques, and tips. The 'gutter' is the space between panels. In the end, if you sell it as comics, it's comics, but that's a commercial criterion, and not appropriate for this mailing list.
Gutters is a mailing list .
It's a bunch of people who want to talk about comics illustrating. In a mailing list , e-mail messages are sent to a central computer, and that computer takes the message and sends a copy to each member. This means that, if you can use electronic mail, you can take part in a mailing list. The first thing you have to do, though, is let the central computer know that you want to be a member. To do that, you subscribe to the mailing list.
