Need help with CJ

[cesspit]

Hi,
I just joined CJ and got some advertisers approved. So I decided to get the HTML link and saw:

Link Type Text Link
PID
AID
Web Site
Encrypt link? Yes
For use in email? Yes
Set link to open a new browser window? Yes
Hide tracking code in link? Yes
SID

Can anyone care to explain what is PID, AID or SID? I'm not sure where to start.
Thanks

PID is your publisher ID
AID is the advertisers ID
SID can be used to identify your specific link, e.g SID=my_cool_website
