I wrote the set system with this sort of thing in mind - so people could make lists of, say, all the comic contest comics ever, their favorites, etc. There are a few problems I've thought of about that though:
1. How do you let users select the comics to be in the set? I can't give people a list of 300,000 checkboxes.
2. The sets could get super huge, which becomes a server pig whenever anyone hits a page that has the whole list of comics on it (like in the dropdown menu).
Usually, these would be tag-team series -- seldom involving more than two users. One way to handle the logistics would be to allow the set creator to "push off" to the list of comics by someone on their favorites list, accessible by a pull-down menu (not on your list? Add them for a moment.)
For instance, the "Bipolarity" series I wrote with DexX: First I'd select all my comics from the series, then bring up his comics through the pull-down, and select all of his. I'd commit the set, and It would include all those comics in chronological order.
I'll let wiser minds than me determine if the set should also be added to DexX's list of sets as well, or not.
