FYI, Lefora is free, but supported by ads - see the bottom of their example page:http://funstuff.lefora.com/headlines/
As 2012 approaches, the ads will become more and more relevant, and even now are quite useful. They'll be relevant, or they'll go.Members can very easily, as detailed above, change the theme to one precisely the same as the default without ads.
But visitors who click on ads will be contributing to the cause.
My cause: bunkers for everyone who wants to be in one come 2012, and designing methods for preserving our culture, knowledge and history.
Budget: $500 million
Possibility of achieving it - about the same odds as the world ending in 2012
I'd hate to be one bunker short because I didn't put ads on the forum
BTW, I have no need for the ad money myself, but you'll have to trust me on that - I won't be publishing my tax return online!
