So, I know that on more than one occasion in my life I've been bored. It happens to all of us (unless there is some exceptionally lucky soul out there). I just found a site that could be good for burning away a few otherwise wasted hours:
Project Gutenberg Distributed Proofreaders. Also, if you'd prefer to just read some free books, you can either check out the well known
Project Gutenberg or the lesser known
Blackmask.
