IntegraMOD

I've been looking everywhere for this nifty little .script, and noticed that this board had it. When users read through posts, there are certain words and phrases that are highlighted and underlined, like "IM Portal" or "Integramod", and, when clicked, they can lead to an on-site or off-site definition or webpage of their own.

How does one accomplish this on other phpbb boards? Is it a mod? Java.script? Where can I find it?

Thanks!

Thanks very much!
