So, I was curious, how many people here actually make an effort to use the referral systems on pet sites? I know I sometimes use them. To see how many referrals I can get from this site. Thus, bringing in members to the pet site that I use a referral link for. I know in the past I used to go all out and use my referral links in signatures on forums around the web. How about you? Do you bother with referral systems, or not really? If you don't, do you find it difficult to refer or do you just send your friends the link of the pet site without using your referral link? Let's share our thoughts on this subject.
