We have put in the basic tracking on various sites to gather the data necessary for our referral program. We have not yet decided on what the rewards will be, so for now you will be participating on speculation that you may get something. Of course, you may not get anything either.... it is still under development.
If you would like to get credit for signing up new users to the BitShares ecosystem then you can add "?r=bts_account_name" after every URL on my blog or bitshares.org.
If someone follows one of your links and ends up registering an account with BitShares via the faucet then "bts_account_name" will be given credit.
We are working out more advanced referral incentives, but this should be good enough to get you all started. Now go and spread links and generate traffic!
