We are using "invite" plugin to people to create blogs on our network.
I wish to create a list of invites sent and converted invites - and display them in a graphical format (attached format)
for example "blog A" refers "blog B" so we will create a list using datatables to display
who referred whom and if "blog B" subscribes and becomes a pro-site we will give a referral fee to "blog A".
I wish to know how and where the referral is stored in the wordpress database table so we could call those fields and make the necessary programming.
