Op, if you base your promotion only on affiliate links, (which are fine as an addition to something else, not good as stand alone form of promotion of your site). I think very few people would actually use your signature. Maybe in addition to referral promotion you consider standard signature campaign here on bitcointalk? You already have good looking signature for that.
Thank you for your suggestion. We just started our second Signature Campaign.
