Ebookvortex invite

eBookVortex is a pretty general eLearning site, with plenty of topics from Oracle to comics, to biographies and memoirs (you'll find all the categories below). While it's no powerhouse, it's a good place for beginners trying to feel things out, and there is certainly some nice content. I've personally enjoyed my stay, and it's easy to gain upload, earn seed bonus, and then claim that bonus. There are also certain little nice things which they offer like allowing you to choose your theme.
