Just so you know, I have a friend who has conjured up this wonderful code that eliminates banner ads added in by your page provider (they are only displayed if the person cannot view frames, whether you have them or not) Here it is:
Paste the code just in front of your real body code for results, and do not edit the above code in any way.

HTML is enabled on these boards, so if you put HTML in your post, it won't show up. Rather, the board will interpret it as real HTML that is hidden from the user.
Besides that, I discourage the use of HTML to block pop-up ads. If everyone used tricks like that, free webhosting would disappear.
