Web2Messenger
(currently Web2Messenger is an invite-only service to ensure that we do not gain more users than our servers can reliably handle)
Web2Messenger.com is a brand-new service that allows people to send you messages from the web to MSN Messenger. You can redirect people to your personal Send Message page, or create your own Send Message page on your blog or personal website.
update:
Web2Messenger now is in public beta.
