Well, it's come to this. It's kind of embarrassing to talk about because it's something that seems simple to do, but I don't know how to do it. But if I want to learn, I gotta ask, so here it goes.

I want to make a comic, right? I just uploaded the cover, so I'm off to a good start. But then I realized I have no idea how to put all of the (soon to come) pages in some sort of folder. I've never done this before, so I'm sorry if I come across as extremely idiotic. If someone can help me, I'd appreciate it. Thanks!

Alternately you can also:

1) Go to the post page
2) Add the tag pool:1234 (where 1234 is the number of the pool you just created [you can find it in the url on the pool page])
