go to:
addons.mozilla.org/extensio...einfo.php

(1) download adblock (i think there are glitches unless you have FF1.5)
(2) right-click on "adblock is enabled" in lower right corner of browser window. on any page, you should be able to find out what images are blockable. if it says "ad" in any of the urls, add to your filter. or just right click and copy and paste each of the urls below:
oascentral.tribe.net/RealMed...!Middle1
pagead2.googlesyndication.com/pag...s.js
images.tribe.net/tribe/js/Adserver.js

there could be more, i'm not a computer techie. but you get the point, add as you go. i don't see anything but the beautiful new look . . .

makes the tribe even more white but hey, it's better than white with ads being the most noticeable elements on the page . . .
