[happyterritory736]

We (Magique) are hosting festival style halloween event at Luna Park Sydney and researching the best methods of promoting.

Currently we use the following networks online:
Facebook
Myspace
Twitter
In the mix

and we have 60 promoters.

Is there anyone online networking tools or methods that you have used or believe would work in helping spread the word??

Contact the Sydney Morning Herald and ask if they wanna do an item on it, written media is still an important means of marketing.
