Is it possible to save a Diablo 3 chat session or save some in game notes

I'd like to take some in-game notes, for example significant items I sold at the AH (with links to the items), some tips or various things I want to remember, etc.

For instance by sending chat messages to myself and saving the log somehow.

Is that possible?

If you're just interested in saving the items you've sold on the Auction House, would not a screenshot work just as well as a note? Simply highlight the item and press PrtSc (by default) and Diablo 3 will snap a picture of whatever you've currently got open.

You could even use this to take screencaps of your chat logs, though you wouldn't be able to click on any links therein.

Pictures go into your C:/Documents/Diablo 3 folder by default (assuming you're on Windows).
