???hi everybody i am here with yet another one of my newbies questions.
i thank you all for responding to me
well whenever someone asks how to get some BTC there is this common answer to joins some sig. camp.
so How exactly does signature campaigns work?
you just put the link they give you inside you sig. area and do your usual postings?
or
you have to post about them, i mean like advertising?
Your assumption is pretty close.
There is a space below your posts where you can put anything as a signature. This signature will be visible to all forum members whenever you post.
Some services 'rent' your signature space. They place their advertisement in that space.
The more you post, the more this advertisement will be visible to people, so they pay you BTC per post. The more you post, the more BTC you earn. But of course, spamming the forum with useless posts is not allowed and may even lead to banning.
See here for all active signature campaigns:
