Not much here, but for those who sell adsense ads on their forum, you may want to consider this add-on.
It basically figures out if user has mozilla already (if yes, don't show ad) and if they don't, it shows an ad for firefox.
It also has a line that will ONLY show the ad on the first pageview, and ONLY if the user is coming from a site other than your own.
JUST REMEMBER to insert your own domain name, pub-id, and channel if one exists.
Just put the following code in to a file, and "include" it in your header file (of footer) - whichever you like.
<%
userAgent = request.serverVariables("HTTP_USER_AGENT") 'get browser
referrer = request.serverVariables("HTTP_REFERER") 'where did the user come from
'response.write useragent
'response.write ("<br />")
'response.write referrer
If inStr(referrer,"DOMAIN NAME HERE") = 0 then
If inStr(userAgent,"MSIE") > 0 or inStr(userAgent,"internet") > 0 or inStr(userAgent,"Opera") > 0 or inStr(userAgent,"Safari") > 0 or inStr(userAgent,"Netscape") > 0 then

We've noticed that your're not using Mozilla Firefox to browse the internet.

Why not try out the new Mozilla Firefox browser for cruising the Billiards Forum:

<script type="text/javascript"><!--
google_ad_client = "pub-###################";
google_ad_width = 180;
google_ad_height = 60;

It is one of the most secure browsers out there today.
