http://www.yellkey.com/ · YellKey.com comes in handy when you want others in a class, meeting, or presentation to open a URL. YellKey is a temporary URL shortener—the longest a shortened URL can last is 24 hours. The advantage of being temporary is that the final part of the shortened URL (a.k.a. the “key”) can be reused, making it unnecessary to use complicated keys. YellKey provides short URLs with common English words that are easy to pronounce and to type. They always start with yellkey.com and end with a random key. An example of a shortened link is yellkey.com/hour . Other “keys” I’ve seen in YellKey’s URLs include happen, small, across, it, know, make, and memory. · You don’t get to choose your key, but if you are unhappy with the key you are given, you can simply enter the full URL again to get a different key.
