Delting mass contacts on msn

How would I mass delete about 100-200 contacts that I've never talked to without opening a chat and then right click delete.

Anybody know a easier way?


Yes I know I spelt the title wrongly.

 

There's a tool on MSN plus called "Contact organizer" (or something of that sort) that lets you easily delete contacts that you haven't talked to for a while (easier than doing it the normal way).

 

Thanks Skele.
