A site for baby names. Search by beginning letter, ending letter, gender, nationality, meaning, or by lists, such as Tolkien names, celebrity names, and most popular. A useful tool for parents-to-be, yes, but also for writers and other creative artists.
For all the writers looking for agents, this website allows to manage your titles, search for agents, and track your submissions. I found it on accident, but it's already helpful.
Site that rents your textbooks to you. The price is about 1/3 the cost and they take the book back at the end of the semester, with the option to buy if you choose. Plus, they plant a tree for every book you rent.
