When you register for a Covert Commissions account, and activate the membership, you are assigned a Covert Commissions ID/member number. All your promo tools will have this number at the end of the links. This protects your affiliate links. 

But you still need to enter your JVZoo, Clickbank, W+ affiliate links in your Profile area to be sure you are credit for, and earn any commissions from sales through your links. You need to sign up for affiliate accounts with them if you have not done so yet.
