Yes, blogspot is free. I believe you only pay if you want fancy features or to have a url without blogspot.com at the end.
If mediafire doesn't work, is it possible to host it on the nexus and make it hidden except for a select few users?
Also, I assume most of us are familiar with torrents, though I'm not sure how one would go about uploading one. (I guess we would all just have to make sure we we're torrenting at the same time, lol.)
I'd get the main homepage up asap before we start getting too complicated on this one forum (or what you were talking about: a nexus forum page just for the mod)
Pool all the resources together on the forum and we'll start calling out what we're working on. Then, post Pics on the blog showing how each of us is coming along.
I'll get started on my first dungeon (starting something simple, as I'm probably the least experienced here), I'll do cavern number 11, generic with spiders.
Also, as I've just released my learning dungeon (called Prisoner's Peak) on the nexus and I'm ready to put some of my new CK skills to the test!
