I'm a little late in posting this, but for those of you who have yet to find this out, Xbox.com now enables you to send and recieve messages for Live through the website. I can't tell you how happy this makes me. It always seemed like a natural course of progression. I just wonder why it took so long. Now I am able to delete all of Xylofreak03's messages while my network is down and I can't access Live.
I love that I can now send out a mass message to everyone on my friends list from my computer. Having to do so through the Xbox controller was such a pain — even for short messages. Considering my laptop is usually sitting next to me while I am playing Live, I can now answer any typed messages through the website rather than having to pause a game for 5-10 minutes while I chicken-peck my message through the controller. Nice.
Other new items of interest on your MyXbox homepage are the ability to see how many friends you have online without having to click on the 'Friends' button. You only have to click on the button now if you want to see who is online. The Box has also added the ability to view players you have recently played with via the 'Recent Players' button — a nice touch. All in all there seems to be a lot of little improvements, especially to the MyXbox homepage as a whole. Head on over there and check it out for yourselves: www.xbox.com
