Hello guys, I report you two ideas that comes by community users of my site.

They ask to write comments on user profiles, that could be erasable if wished by subject user.
Also they should be archivable manually or automatically after some time.

And last but not least, they ask to rate members profile

If you like these ideas, I could extend this suggestion with some little feature more, so it could be cool

Comments for profiles is like a profile guestbook.
there are a lot of guestbook threads if you want to see what it is about.
