For those of you that had always wanted to send messages to offline contacts, this is the way you can achieve it without any mobile use involved.
Go to
www.offlinemessenger.com
The instructions on the site are plain and simple, you click on the
mirrors section and from there you choose one of the
online bots and add it to your contacts list in msn.
It has to be online in order for the offline messaging to work. Once you've reached that point, open a conversation window with the bot and follow the instructions it provides to start sending messages.
Happy offline messaging.
