Digital publishing is getting very affordable.
I had a look into it, and Blurb do high quality digital printing for pretty cheap.
If we had enough material collected, from events and forum posts, we could print it and each walk away with a good copy, and even put some in the library.
We could even run an essay competition once a year, and put those submissions in the collection.
If we printed 25 paperback, black and white books of up to 60 pages, they’d cost about $8 each including shipping. http://au.blurb.com/pricing#trade
