Who's installed it? I now have five messengers installed on my computer. Fun.
It's quite nice I suppose even though I haven't added any of my friends to it yet. Just Tom, who once again sneaks in even if you've deleted him before. It's good that it reminds you when you've got messages etc and looks quite pretty.
Though it's welcome I do wish they'd just clean up their code and include a spell checker and other basic things rather than add all these new features all the time.
