Thank you once again for the fast reply and helpful answer.
Should anyone else look to do this as well, here are some finer details:
Create a New Auto Action:
1 - Triggers: Before First Login
2 - Type: Query
3 - Action: Query
Code:
INSERTĀ INTO `idevaff_affiliates` (`username`, `approved`, `payable`, `f_name`, `l_name`,
`email`, `address_1`, `city`, `state`, `zip`, `country`, `phone`, `type`, `level`,
`signup_date`, `ip`) VALUES ("[username]", 1, "[name]", "[firstname]", "[lastname]", "[email]",
"[address]", "[city]", "[state]", "[zipcode]", "[country]", "[phone]", 1, 1, NOW()+0,
"[registeripaddr]");
INSERTĀ INTO `idevaff_tiers` (`parent`, `child`) VALUES ("[cb_sponsor]", "[cb_member]");
4 - Action: Mode -> External
5 - Action: Host -> Localhost (in my case, the db is on the same host)
6 - Action: Username/Password/Database -> use whatever to setup on install of iDevAffiliate
7 - Action: Charset / Table Prefix -> left blank as unused
Note: On my install I synchronized the iDev users ID with my CB user ID and I have stored each user ID in the CB field cb_member and recorded the cb_sponor number at registration. This allows me to automatically create a connection between the two on registration in CB and setup a Tier connection in iDevAffiliate (which is the second INSERT above. If you don't need it, you can delete it.
