[this was an update to the last post, but I think this deserves a new one]
Take your WM5 Device and type this in: http://mobile.live.com/wlm
This is Windows Live Mobile Messenger Web Application [BETA] - it rocks!
I just loaded it up with my second messanger account and have been having fun with it for few minutes - it works!
There is no live refresh of the page when someone sends you a message, but that's ok - since the message on the screen of your pal will show that you ARE using a mobile device and we all know what that means when we see that while chatting with someone online.
Basically - this will save me some txt messages and their 160 character limits from going back and forth. [I know I ought to just start sending MMS]
I would simply login to my second messanger account, which I have designated to my friends as my mobile only contact base.
I'm excited. I love communication options and this is another great one.
