Do you still have some of these that are not spoken for yet?

I've been watching bitcoin for a long time and started mining a couple of months ago using a few block eruptors.  I've made the decision to upgrade my mining rig and should hopefully be able to get some more mining hardware soon.

What do you guys recommend as required reading from someone just getting started?  I'm not looking to get rich mining but I do see it as an interesting hobby and I would love to learn as much as I can so that I can make the most of it as well as become a part of the community and learn more about crypto currency in general.

Thanks for readying this and for any info that you might provide.
