As per requested in
this thread.
What it does:
When you set your WLM status as busy, it will automatically send a message(which can be changed) to and then block anyone who tries to talk to you. It will then unblock that contact after a certain amount of time (which can also be changed).
How to use:
First make sure the script is enabled in Plus Prefs. Then simply set your status as busy. You can customize the unblock delay and message sent to your contacts through the Options window (accesed by the Plus! icon in chat windows/contact list> Busy Blocker> Options).
