Hello, I'm a new member of this forum. I'm new to bitcoin too and just start to earn it through foucet. I heard that there is a signature contest in which member can earn bitcoin via posting and i want to know how to participate. Basically you advertise their site through your signature, right?
as a newbie you shouldnt worry about joining a signature campaign just yet. i suggest gaining a rank on this forum, getting a feel for the community here and then finding a company or product that you would like to promote and start using that for your signature.
