I am on the verge of launching my ICO and want to buy a bitcointalk Hero Member account.
Is there any place where these accounts are sold?
Also I want to run a signature campaign. Kindly someone explain to me what a signature campaign is and how to run it?
A hero member account is not needed for you to run your signature campaign here in this forum. The thing is, you need to have first signatures that have codes that has the necessities for your campaign. For example, the link for your facebook account and everything. A signature campaign helps you advertise your ICO in this forum.
