You probably downloaded the MSN Messenger Activity SDK but there's also the Windows Messenger SDK which allows to do more with MSN Messenger. Too bad it's the same API which the old Windows Messenger uses - there's no way to communicate with MSN Messenger without having to install Window Messenger unless you use this Activity SDK which doesn't offer much, I guess.
I hope that they will add more advanced API commands to the next version/s which won't require Windows Messenger installed too.
Yeah, i did. The MSN Messenger Activity SDK was what i downloaded. Like a lot of people i uninstalled Windows Messenger and only use MSN. I see no point in using the windows messenger api, kinda useless to publish since so few use it. Except maybe companies internally, since you can setup your own windows messenger server (or so i have been told) and thereby not rely on MSN servers
