In the new MSN Messenger (MSN 8 - Live), there is the possibility for 'offline messaging'.
You can type a message to an offline user, and the message gets delivered when that person signs in. I *guess* it has something to do with the new protocol. (the message gets stored on the server?)
Anyway, before that, "msn plus!" had a similar option: you could type a come-back message to an offline user. That message was stored locally, and delivered as soon as both you and that contact were online.
Could aMSN have a similar function?
Sometimes a have something to say to someone, but (s)he is offline, and I forget what I wanted to say when they are finally online. So a "come-back" message would be handy
Just a suggestion...
