Recording your friends in your Log Book

i'm not sure what the log book does but i saw a pic about it and it looks like it tells us about the monsters.

My idea is that the players has an username/id that we can search/add/right click there name to record it to your log book when your in multiplayer . And then the players can create their profile and add a description about​

themselves and that description will be shown in the log book but first the person you're adding should accept it
first before it gets recording in your log book. It will show the person's equipment and other stuff

 

I'd enjoy a log book.

 

I support this, but I don't want somebody cataloging me in PVP..

 

that's a good idea. i would enjoy seeing all my enemies info!
