well i had some trouble logging into messenger 8 beta so i uninstalled it, it was saying something about m not being able2 login with my ID or something.... oh well, it didn't look 2 impressive so far 2 tell ya the truth...
thats why its the beta, so you can give them feedback on the problems that its having, HENCE BETA!!! Thats the lazy factor of a company kicking in, they dont feel like hiring testers, or keeping testers employed longer to find more bugs, so they shove it out to the oh so eager to test public!
