Check this out....I got this info from Steve Case's office...
f you do not want to receive pop-up advertisements when you sign on to America Online, please use keyword: MARKETING PREFS, and choose "Tell Us What Your Pop-Up Preferences Are." Once in this screen, you will see a button in the lower right hand corner which says "If you prefer not to receive any special member pop-up offers, click here." Click on this button.
Once you click on this, another box will appear and confirm: "I prefer not to receive special member benefit popup offers from AOL." You must click on the small square that comes before this sentence. An "X" should appear in the box. Once you have done this you can click on "OK" and your request will be completed.
I know I hate those offers....
