well there is a signature code we have to add in different forums. then we must make a thread on this site indicating all those sites that we have added the signature. there are new signatures to add. the old ones are not accepted. and so i have updated my signature already in every forums. there are more ways to earn from this site that to earn from signature. we can earn by Stumble upon the links given -by the admin. all of the offers are in this site. just search for them.
