I emailed into Adsense support a week or so ago about being able to incorporate a feature with Adsense and Google Calendar. What I want to do is be able to attach notes to changes I make with Adsense:
6/18/2006 - Added in Adlinks to the left side of the website 6/14/2006 - Switched from 468x60 to the Leaderboard on the top of every page 6/10/2006 - Changed the BGColor of the homepage ad unit from #CCCCCC to #FFFFFF
Right now I am just using Outlook/Excel to track it all, but it would be great to be able to track it within Adsense itself so it is always available. Plus, for those who aren't currently tracking changes, it would be a great way for them to start, as that type of info is invaluable to fine tuning.
I figure if other people think it's a good way to track that maybe it will happen.
Thoughts or suggestions as to what you use to track changes?
