Just as ally grades that allow some rights for members (online status, ally message, etc...), it could be very nice to have some different friends types :
- friends
- commercials

Commercials does not allow you to see the online status, for example.

It would be really easier than having notes with the name of the player you trade with, that sometimes changes nickname, now the First Planet can move, etc...

Yes, and its precisely why I don't put in it some commercial contacts, that (for a most of them) I contact more often than my buddies
