Hello,
I am new to Bitcore. What is this Avatar campaign and how can one get involved? Thanks.
For first i would recommend to read the first posting of this topic. The OP (opening post) will give you the answer to your questions in 99,99 of all cases.
Besides this, i am afraid that you can´t participate in this campaign, because your rank in this forum (you are displayed as newbie atm) is too low to wear any of the signatures at all.
