That is what I meant...
Messenger Plus! by Patchou is better than Messenger Plus Plus from www.munet.net
As far as I can see, they have some SMS plug-ins there designed to integrate with Windows Messenger, unfortuantely I don't have too much programming experience, so I don't know exactly how that would work. Anyways, just a suggestion.
PS. Getting SMS'd about a name change would indeed be annoying, but it was just a suggestion along the same lines. I know I would definately not have that option turned on.
