Plugin makes shorter URL and counts number of clicks

Short URL Plugin allows you to create shorter URL’s and keeps track of how many times a link has been clicked. It’s useful for managing downloads, keeping track of outbound links and for masking URL’s. Clicking the Clear All Clicks button will reset the count for each entry.
It includes pagination of links, easy setup of htaccess (permalinks) and allows admins to pass variables to their redirects. It also allows customisation of the permalink.

After installing, you go to Plugins -> ShortURL to make shorter URLs and use them in your posts. Maybe the usage is so easy that I don't need to guide more, just install and use it.
