I would like to create a "profile" that is for my use only.

As I read articles and comments, I form my own "opinion" profile that is descriptive of that person, and I would like the ability to "add notes" that are only on my computer, and only for my "memory" assistance. That way I can easily recall who I like and don't like and WHY. So if I think someone is off in la la land, I can make that "note" and if I think someone is really great I can note why and see that in my personal profile notes about authors and commenters. That way each SA user would have the ability to create their own "notes" about the other people that they are reading about and easily refer back to that as they are reading comments and articles. I really enjoy the SA forum and thought this would help people sort through the things they are reading.
