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?
Simply first upgrade your rank ( like everyone advise you ). I will tell you one thing, if you wish to enter in some good signature campaign you need quality post`s. You see, when you apply for good signature campaign manager of campaign will review your posts and tell you will you accepted or not. So cause of that you need to make good comments if you wish to be in good campaign when you become some higher rank.
If you are just high rank you can be refused, check signature campaigns threads and you will see.
