This site is awesome. It lets you set up a very simple and easily customizable page to direct people to all of your pages and places. It didn't take me long to set up at all. I had already made the image for the background to use on my Twitter profile, so all I really had to do was upload that, change some fonts and colors, and type in my information! Oh, and add links to everything, of course!
The URL for my About.Me page is the one that I'll be putting in email and forum signatures from now on. And it'll go on the business cards I'm going to get one day (when I can afford it)! I'm really excited that I was able to solve my problem so easily, and I highly recommend using this to save yourself from having to choose which URL to give out to people.
