People please...
The MSN service is/was having some hickups and they were conducting tests with the new Beta, like you can read everywhere.
It is of no use that everybody posts that he/she can't log in and then after an hour posting back that you can log in... This is not needed and is spam.
Just be patient, and try to log in from time to time and refrain from spamming threads like this (this is the third one I come across in the last half hour!). The services will always be up again in no time...
If you can't live without MSN then that's too bad, but still that is no reason to start spamming unneeded posts. If you think another IM service (like AIM) is any better, then think again. They too have problems and maintenance to do.
If you don't believe that then simple use another IM service instead of bashing MS/MSN because _that_ is BS, not the fact that MS/MSN does some maintenance or is testing the Beta software so you (yes you!) will have an official released msn messenger 7 on time...

Sorry for being so blunt, but yeah, some people
