You’d think there would be an easy reference to this somewhere, but it is spread all over the place. So, here it is for easy reference.

Linking AIM, MSN, Yahoo, and Skype from a webpage … the following goes into the href attribute on the anchor tag.

AOLIM : aim:goim?screenname=AIMScreenName

MSN : msnim:chat?contact=PassportID

Yahoo! : ymsgr:im?user=YahooIDHere

Skype : skype:SkypeUserName

*Note: the MSN link only works in the newer versions of the client.

If you know how to link to screen names on other services shoot me an email and I’ll add it.
