What I have planned is basically a dropdown exchange, but more elaborate and robust than what you're used to seeing on here.
Before I explain how it works, it's not going to be all-inclusive. The ceiling will be between 10 and 15 comics and the criteria for joining is pretty specific. The purpose of this network is "strength in numbers" -- Sharing traffic between high quality websites. If a reader likes any of them, he or she will likely find something to like in all of them. That's the goal.
Here's the gist of how it works:
There will be a network "capsule" on each site in the network. Inside the capsule will be, on the left, an image for the network and a dropdown selector below it. On the right of that will be a small content area that has blurb about the network. now, when you select a comic from the menu, the content area will change to show a small image specific to the selected comic and also show a blurb of text describing the selected comic. there will then be a "go" button to click and go to that website.
this network capsule will be very professional and slick looking, and putting it on a webpage will be a simple matter of pasting the source code. All of the content generated on it for the images and text and what's in the menu will be referenced from my server.
Now, onto the criteria. There are a few I can go over.
1) First and foremost, I have to personally think your comic is good and capable of sustaining traffic. This is more the "x factor" that's harder to quantify and partially subject to my personal taste.
2) The overall theme of the network is "imaginative". Nothing derivative. Dorks who play video games, college room mates, etc. Comics are very unlikely to be accepted.
3) There is a preference towards aliens/zombies/other planets, but it is NOT a requirement.
4) humor based or story based are both fine. my comic is a combination of both.
5) you have to have an update schedule declared on your website and you have to stick to it consistently. Quality, reliable, imaginative websites is the idea here.
6) a good looking website layout that fits together with the theme of your comic is a big plus, but not a requirement.
7) there are no pre-existing traffic requirements, but having better traffic is always a plus.
8) color is highly preferred.
9) comics that update 3 to 5 times a week need at least 20 comics archived to be considered. comics updating 1 or 2 times a week require at least 10. This is flexible if your work is outstanding.
The plan is to start with the network capsule being what comprises the entire network, but if all things work out, eventually it could become more integrated and have a hub site (ala http://www.dayfreepress.com
