AutoLink from Jesse Ruderman is a Greasemonkey User Script that will turn plain text links like http://www.digitalmediaminute.com/
[email protected] into clickable links.
All the reservations that developers have been voicing recently about using Greasemonkey scripts aside, this looks like a pretty nifty tool, and Ruderman supplies you with an example code snippet that will help you to add new filters that you can use if you know your way around JavaScript regular expressions.
This tool is very handy especially if you’re a web publisher because usually when you supply someone with an e-mail address or URL, what you really want is to give them an easy way to simply click through to the location.
