Yeah, so this is kind of dead. I've been sick the past week, didn't go out, and I read books mostly on a bus, because when I'm at home I can't tear myself away from the screen. And when I'm at my computer, my creative lobe apparently don't work at all, and without them coming up with new creatures is kind of hard. Plus, even with my creative lobe, frankly, the jellyfish challenge adds even more to my feeling of pointlessness about this project.
But in case this somehow continues, but it would be, actually, much better if it restarted, I've realised how a wiki could be useful for it.
First, every creature could get its own page, with whatever description and illustration the author has provided, and then the page easily edited for any new info, and linked philogenetically to other creature pages.
Second, any topical ramblings, which would be detrimental to participation on the forums, could go to their own page. And then also easily edited by anyone willing to improve their readability and other properties.
I feel like soon it would be a great time to finally learn to work with Google sites, and I could take that as a test project. Although "soon" here is a variable of some kind.
