How do you shorten URLs in twitter?

[meegs]

I've noticed in a lot of posts that people are able to shorten URLs. In the Help section, it says that if it's more than 30 characters long it shortens automatically.. I tried, but it didn't work.

Any ideas how to shorten URLs?

The URL automatically turns into tiny url by itself in twitter. In case it's not happening then go to http://www.tinyurl.com/ and enter your long URL to make it tiny.
