If you need to send a letter through snail-mail (the postal system), there's a service that allows you to do this for free--no postage costs at all! It's called eSnailer. You can use their site to compose a letter using their editing tool. You then get to address it, and it gets sent in the postal system to the recipient. All for free. I have no idea how they manage to do this without charging since they are already making it easier to send a letter. Instead of typing it out then printing, then addressing the envelope, then attaching postage, and then getting it to the post office, you just type it up and they take care of all the rest.
