Could anybody give me any suggestion how to welcome new affiliate to become active or shall I say not just join and leave. I was able to get five new affiliate but all of them are not active. I never knew them and just get them through advertising.

Just be creative, Ethan. Try putting yourself in their shoes - what would you think should impress you if you get a message from your sponsor?

If I were your referral, I wouldn't mind being welcomed with a premium upgrade

But seriously, if they include their email address, I might contact them to let them know if they have any questions about ClixSense, I am available to help. I mention the other earning opportunities on this site- ClixGrid, Tasks, adding the toolbar, etc.
I use my personal message to my referrals to make them aware that I am available to them if they have questions about making more money with ClixSense. In many cases, this is the only chance to communicate with new referrals who choose to keep their email addresses private.
