Kill Yahoo Chat Room Ads...
Create a new text document, copy and paste the following...
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Yahoo\Pager\yurl]
"Finance Disclaimer"="http://msg.edit.yahoo.com/config/jlb"
"Chat Adurl"="http://chat.yahoo.com/c/msg/tabs.html?spaceid=21501837"
Doesn't matter what you name it, as long as you change it from .txt to .reg.
It works well with my Yahoo, should work the same for everyone else as well.
