Wow, I wasn't expecting any replies this quickly. In answer to your questions:
1) Five pages completed, with several more sketched.
2) The idea and characters have been around for about four years, but it's only recently that I've been able to pull it together into something coherent enough that I could start making pages. I have most of the first chapter thumbnailed and scripted, which comes out as about twenty pages. It's definitely going to be a long-term project; I have the plot pretty well worked out for about two years worth of updates, and a rougher idea for after that.
3) The website will most likely be mainly about the comic, though I plan to have a section for unrelated art as well.
4) There's just a few more things left to do with the site, so I can probably have something to show within the week.
5) I haven't used FTP much, but I have a pretty good idea of how it works. SSH I've never used.
6) I don't have that much complete just yet, but can post the sketches for a good portion of the first chapter. Would that suffice?
Again, thank you so much for taking the time to reply. I'll try to have all the necessary material ready as soon as possible.
