MSN Messenger 6.0 (Preview) is here!
Seems MS is a little bit slow with updating the sites mentioned in their press release, but you can download it from this link.
[Update] Cool, I'm using "Neo" as graphic (there isn't a .NET logo available yet ;-):
IM me @ jan@leadit.be.
You can get more graphics and smileys at www.mess.be.
