If you want to become a Pyramining member you need to find a sponsor. To select your sponsor you must have an
active referral link. Referral links do expire, so in case your first link won't work, try another one. After a referral link
is successfully selected, you will be able to join.
Selecting a sponsor gives him/her the chance to increase his/her reward, so it would be polite to use one of the referral links of the person
who brought you here.
However, if you still don't know where to get one, try to search withGoogle.
Please don't post messages on the official thread on the bitcointalk forum. It's considered annoying and should be discouraged. Also I invite you to not use links found on the
official thread, in order to discourage this practice. The official thread should be used only for Pyramining support.
