A Cool URL Shortener
AND - YOU CAN SET IT TO EXPIRE!
You may have noticed that goo.gl shortener went away, so you might like this replacement. It is yellkey.
WHO WILL LIKE IT? Teachers that frequently share URLs in class but have issues with students using URL shorteners.
HOW DO WE USE IT? Visit http://www.yellkey.com/, paste in the URL to share, select a length of time for the key to exist, generate yellkey and share!
WHEN TO USE IT: Yellkey is great for situations that need to share a URL, but it does not need to be permanent. A good example is when you have a group presentation and they just need to quickly have access.
In the classroom, it is great for those quick websites that may not be shared links elsewhere.
