I'm going to help you guys get rid of Meebo. I blacklisted that nonsense the first time it popped up. Although I can't understand why you cons have a problem with unfettered Capitalism at work! Must be the sociaslist in us all!
In IE go to TOOLS/INTERNET OPTIONS/SECURITY then click on RESTRICTED SITES then click SITES. A new window pops up. Type the following URL (address) in the list box titled "add this website to the zone" WWW.MEEBO.COM Click ADD/CLOSE/OK Close and then reopen the browser and you should be Mebbo free.
Ewwww...Internet Explorer. Just install Firefox and download the add-on "Adblock Plus." Problem solved. I think IE even puts in a cap on the number of ads it will block in a day, so there really is no point to use that browser at all.
