The guy who makes Friendship is Dragons here. It's really early in the morning and I can't sleep, so I'm going to shoot down your idea without mercy. Sorry.
I don't think there's any such thing as a "community" tabletop roleplaying campaign, as if it were a service or obligation to the group. It's always between a handful of friends, or at least a gathering of sufficiently like-minded strangers. You know, people who share a mutual understanding that they'll go the extra mile to commit to this kind of thing as a hobby. You're not going to find that group by standing in the middle of a general public crowd and shouting, "HEY, WHO WANTS TO START UP A PATHFINDER CAMPAIGN?!?!?!"
What's so special about a group of webcomickers playing an RPG, anyway? It's just like a group of anyone else playing an RPG - they put their day job behind and just enjoy playing as someone else for a while. Literally nothing different or special would come out of it. So starting a roleplaying forum for purely ComicFury roleplayers seems a bit silly. Better to just find a group and then figure out amongst yourselves the best way to transmit information.
Asking for, of all things, a webcomic to come out of it is just plain greedy. To say nothing of the effort that would have to be put into it, what guarantee is there that the content of the campaign will be worth making a webcomic about? There's a saying that "A D&D campaign would not make a good movie/book, and a movie/book would not make a good D&D campaign," or something along those lines, and it's a saying for a reason. Even for those of us that make comics about D&D and be as true to the subject matter as possible, the fact remains that we're making stories here that, at best, reflect the most important parts of D&D - not actually simulate the experience to 100% accuracy. No matter how compelling the campaign for the players, there will always have to be some retooling of what actually happened to make a cohesive story, and at that point it's not really about the campaign, is it?
TL;DR: Start a Pathfinder game with your friends because Pathfinder is a fun game, and because roleplaying is an incredible social experience. NOT because you want to start a popularity movement. Goodnight.
Nowadays, I also abide by the rule of "If it's my work, I don't create the page nor edit it." It's surprisingly easy to tell when an author is describing their own work, if you know what you're looking for.
I treat gaining a TVTropes page as an accomplishment. If someone with no obligations took the time to make one for the comic, then something has clearly been done right. If an edit is made to cover a certain event in the comic, that must have been significant enough to be noteworthy. It's an opportunity to watch how strangers on the Internet describe, perceive, and analyze the comic.
Also, not really an active enough wiki-er to make a habit of editing public pages. *shrug* Still, it's a nice source of views - about 1 in 24 visitors per day.
I'd like to count the number of comments there are on each comic page and display that number. "There are X Comments" or something like that. At the very least, I want to know: How would I go about doing this? Thanks.
A screencap comic of My Little Pony: Friendship is Magic. Equestria is a custom campaign setting for Dungeons and Dragons, and the mane six are Player Characters. How will a party of six roleplayers fare in a world where the usual hack-'n'-slash high fantasy has been replaced by pastel-colored ponies?
