I used to co-author a webcomic.
1) How much time in general does it take (like umm in a week)?
We tended to take as much as it took to do the strip, sometimes ten minutes, sometimes three hours. It depends what you're doing and how many times you feel you need to redo it. Heh.
2) Do you have your whole story written from beginning to end?
We worked on a per-gag per-strip basis with small pockets of ongoing story.
If your comic does have a difinitive end, then it would be a good idea to at least have SOME small inclination of how it will turn out at the end, it will help to not drive your comic into a hole and give it some direction.
3) What equipment do you use (like scanners, I dunno...)?
We did from-scratch pixel art done in Graphics Gale.
4) Is there a specific page format?
No.
5) How many strips must be prepared before launching a comic?
However many you feel.
6) Have you ever followed a drawing / comic class?
Nope.
7) Does it permanently make your stress-o-meter go up?
If you let it.
Some of these questions are quite worrying. You should only ever, ever do a webcomic if you enjoy it. You should do it how you want to, when you want to. It's your comic and relying on other people is no way to do things.
Sitting up one day and thinking "Damn I'ld like to do a webcomic. I wonder how everyone else does it." Is not a very good train of thought, if you want to tell a story and feel like the only suitable way to do it is through the medium of webcomic, then that's the best way. Don't follow anyone else, follow yourself.
For instance, we created three brilliant characters for something completely different, we fleshed them out and thought of some pretty cool stuff they could do, we found them funny and enjoyable and wanted to share them with the world. At first we were doing a single Flash video, but eventually we decided a webcomic instead.
As for fanbase, we had about three, haha. We went on because we liked doing it and only stopped because we felt the well of fun had run dry, ideas were few and far between. You can be sure that doing a story-based comic is much easier to write than a pure gag-based one.
