Add row into mysql upon registration

[Nullifi3d]

I have a mod installed (my own) and I am redesigning the mysql structure. I decided to create it's own mysql table (banners). I need a row for every user.
Code to run upon registration:

PHP Code:

$db->query_write("INSERT INTO " . TABLE_PREFIX . "banners (userid, username, title, url, html, ext, width, height, clicks, available, impressions, status) VALUES ('$userid', '$username', '', '', '', '', '', '', 0, 0, 0, inactive)"); 


Will this code work in register_addmember_complete and is that the beast hook location to use for what I want to achieve?

Also, if I want to remove the row upon user deletion how would I go about doing so?

Please only reply if you are 100% certain your instructions are correct. This is being put into a live install.
