Hi there,
I'm an old time forum lurker, registered here a while ago when I was trying to decide what eReader to get ( and discovered I can't have the one I picked hehe) and anyway, I found this today and thought I would share, maybe someone would find it helpful. Basically it's a blog about books and so on and the author usually posts about free ebooks as well. If this has been posted before please have my excuses in advance.

Have a bright day.
