I did not know that they plan to run another bounty campaign. First one was on three forums, nearly dead altcointalks and cryptotalks, and here. Here, I havent noticed their signature being here and there. I would suggest them to concentrate only on this topic and only on signature campaign. Twitter and facebook are nice places to gather attention and new users, but bounty hunters mostly share all the info among each other. So it is quite ineffective. Those who wanted, already registered there. I have noticed that on bitcointalk number of signature campaigns that pays in Bitcoin have decreased. So running a campaign with small payment will also do.
