Now you can send instant messages from the Windows Live Hotmail and People pages! This means that, even if you’re on a public computer where Windows Live Messenger isn’t installed, you can still send IMs to your Messenger contacts.

Customers in Brazil, Canada, China, Germany, the Netherlands, Norway, and USA will see this feature for the first time today (as usual, rollout to different individuals is gradual, so if you don’t see it yet, please be patient). This feature rolled out to users in France, Italy, Japan, Mexico, Spain, and the UK last month. Not in your area yet? We will be rolling out web-based Messenger to more locations in the coming months.
