Well, I was thinking on the possibility of creating different kind of groups in buddies.
I put this idea here because improves a bit the communication between players being more organized.
Until now, he have this in buddie list:

Nr: Number of Buddy
Nickname: Nick of the player
Points: Points of the player
Alliance: Alliance (if the player has)
Coordinates: Homeworld
Actions: Write message/delete friend
-----
My idea would be to add a Group column in which we can add a player to a group we can choose such as:

- Deuterium Seller
- Deuterium Buyer
- Friend
- Alliance Partner
- Bait (if someone puts his account to your service to stamp other players)
(these are examples, if you like this idea give ideas of different groups! )
Only to have the buddy list well organized and also would help players if any day someone lets his account to another player to know who is each player
