Header, template and MSN Spaces

I adapted the background picture of the header while trying to keep the original style of the template.
I played with MSN Spaces for a while last night on a Windows machine and I have to say that MS did it quite well. There are a number of fancy .Net features e.g. drag&drop layouting plus photo albums. It is nicely integrated into MSN messenger 7. I was quite happy. But there are still some drawbacks:
1. Compatibility. Well, it is expectable while bearing the name "MS"N Spaces. I need IE6 to see those features.
2. Customization. I spent quite a while trying to figure out how could I change the out look (I am not satisfied by those templates MS offered, although there are a lot. And I am critical to the appearance), but I can't find a way to set one of my drawing as the background, neither as the header. There seems no way to edit the code either. Good or bad? Depends.
3. One ID one space.
4. Lack of spell checker.
Conclusion: It is a very nice feature that MS offered. My friends are sticking there and blogging everyday. It seems they won't move to any other instance messenger recently. MS won again. I saw many non-blog people started blogging by sharing their photos first. But I won't be able to join them simplely because I am using a sh!t Mac and I don't care much if my friends' goin to read my blog or not. The world is now MS's and I am also expecting a major update of MSN messenger:Mac, which was announced during the WWDC keynote.
