Can someone names some Cheap or free ways of advertising, ?

I think the best place to advertise some good cause is social media. Make profiles on Myspace.com, facebook, twitter etc. You open a group there, make more frenz and pass the msg through group discussion, funwall superwall posts. This way you can inform them + know the feedback of people.. If you have a web page.Use stumbleupon, digg, del.icio.us (social bookmarking) sites to let people know about it. The other method is by article posting, press release and news release. There are many sites that allow you to post articles press or news release for Free or for really less price. Participate in forums. Google for blogs that talk about the similar topic. leave comment there. If you can be active in all this. You can really spread the word out and the best thing about it all is that it is almost free..
Good Luck !!!
