I don't really understand, if you mean a automatic status changer, then it has one if you are away for so long or w/e... or if you mean a comeback message, then you can do this by right-clicking on the person who is offline, going to 'messenger plus! extras, and click 'set comeback message', and the next time he is online when you are, it will send him the message that you wrote earlier...
if you mean an offline talker, stuffplug ng 2 can do this, and you can download it from here:
www.stuffplug.com
for the stuffplug 'offline talker' to work, you have to block the contact, and you can talk to them while they're blocked, making it appear that you are offline.
