Just type webmessenger.yahoo.com into the address bar of any web browser. That’s w-e-b-m-e-s-s-e-n-g-e-r. Messenger – it’s on the Web, Jeb!

(You might be prompted to install Adobe Flash 9. It’s the only thing your browser needs to run Yahoo! Messenger for the Web. You can click here to find out what version of Flash is currently running.)

At webmessenger.yahoo.com, either click Sign In or Sign in as Invisible.

Sign In logs you in as “Available” – so anyone with you in their Messenger list can see that you’re online.

Sign in as Invisible logs you in, but keeps that information private. No one else sees you.

To sign out, click Sign Out in the upper-left corner of the window.
