Subscribe-O-Matic is a unique awareness and advertising system that operates within the Second Life virtual world.
It works on the principle of voluntary membership of each group, while those in charge of each group in turn enable their members to send at any time text messages, images, items or documents on a map.
The title 'Second Life Gadget of the Year 2007' was, among other things, well-deserved above all due to its 'user-friendly' nature – it is completely voluntary, really easy to use and most importantly does not permit unwanted or accidental spam.
