I read a half-dozen or so webcomics. Since I always read a comic chronologically through a site's archives, I would like to be able to keep track of which comic I left off reading. My idea is for a script that would be able to bookmark the last comic I read, and take me back there next time I visited the site. (Maybe via a link?)

The trouble is, I'm still a novice Greasemonkey hacker, so I have no idea how to go about coding this. I'm thinking it would require cookies, though.
Ideas?

Why not just have Greasemonkey add a style so that visited links turn another color and there will be a row of black links if you go in chronological order, then you can just go to the last black one and start off on the one after that.

but if you give me the site, I'm sure I could whip this up. And no, no cookies. I would use GM_setValue.

Why write a script to bookmark a page when that function is included since years in all web-browser?

OK, here's the sites I visit. These have archives as a list:

http://xkcd.com/archive/
http://www.asofterworld.com/archive.php
http://www.thinkin-lincoln.com/index.php?view=a...
http://www.smbc-comics.com/archive/

Achewood is an exception, and uses a much different format:

Yes, I know how to use bookmarks. However, it's a nuisance to make a bookmark after every time you read, to keep your place, and you have to periodically go clean out the old bookmarks. It's tedious and inelegant.

Yeah that script would actually be pretty easy. I'll make a userscript command so you can click it and it will take you to the last comic page viewed.

halide - Try the Hilarious Webcomic Manager extension for Firefox. Vey easy way to keep track of comics.
