How to allow certain HTML codes in comments?

This has been asked many times before.
A search will show many useful threads.

I have searched the documentation and the forums for help with controlling how html is handled in comments, to no avail.

Could someone kindly point me toward any relevant articles concerning this?

The file that you need is
/wp-includes/kses.php

Thank you Podz, but as a novice, I need a bit more information. Is there any documentation regarding how to alter this file to alter or disable html in comments only? Similar to how this submit area only allows these specified tags (a em strong code ul ol li blockquote).

For anyone else concerned with this issue, I believe I found some helpful docs here.

Thanks again, Podz!!
