This is my first Instructable and it's on how to remove the ad from the top of your AIM buddy list. Personally I can't stand the thing and if you can't either.. or just want to get rid of it, carry on to step one!
This image is a screenshot of my version of AIM (18.104.22.168). As you can see the ad is gone! I also just painted over my screen name above the "Enter status message here..." text box. It's not a side effect of the Instructable. Enjoy!
Step 1: Close out AIM
Make sure AIM is not open (not just signed out). Right click the AIM icon in the lower right hand corner if it's there and click "Exit AIM".
