Signature campaign started way back June 12th 2011 and before now mining, offering services, Bounties, project participation, Tipping, donations and signature free-promotions were ways users earned from the forum but the introduction of signature campaign crippled other services even though most of them are still active but yet it doesn't generate much traffic anymore.

Most of the other options if well utilised might even generate more fund for participants compared to signature campaign. And This ignorance makes new users with skills that can fetch them more on the forum focus on trying hard to rank up so the can participate without knowing their skills if advertised on the forum can earn them more and the will also receive the same BTC currency for their services
