Okay. I'm a member of Vicktor's fleet but I think I have entirely different idea about the kind of social tools that would help player groups work together more cooperatively. Here are a few concrete ideas that I think would benefit everyone in the game, not just player groups but individual 'lone wolf' commanders as well. I'd love to hear any criticism as to why any of these features would be "bad" for Elite.
1. The ability to sort my friends list. I have friends from my expeditions into the Formidine Rift, Friends from the Earth Defense Fleet, Friends from pre-release beta, Friends from my time with the Children of Raxxla. Lots of friends but no way to group them in a way that makes sense. When I'm out in the Formidine Rift looking for the answers to the Galaxy's mysteries ... I want to see my Rift buddies and could care less about my peeps in the EDF (no offense guys, just not running missions for EDF right then!). Likewise when I'm back in the Bubble I'm more concerned about seeing the members of my PMF. Right now its all jumbled. Better tools to organize our friends list would be a nice feature that anyone could choose to use or to ignore.
2. Mail. There is already a nice tab in the Comms box for messages from NPCs that I can open as soon as I log in and get updates on stuff like missed deadlines. I'd really love the ability to send and receive messages to and from my friends. There was a scene in Imprint, the novella that game with 1991's Elite: Plus where the main character received a mail message while at a station. I loved reading that and want that kind of basic feature in the game. Sometimes when one of my game friends has been offline for a while I'd like to be able to "ping" them just to make sure everything is okay without having to be online at the same time. I have friends all over the planet in different timezones and we can't always be online at the same time.
3. Minor Faction Tags. The need for this is less obvious for the Lone Wolf type but let me try and make a case. The way I'd like Minor Faction Tags to work would be to have them handled by the game mechanics and not by "Fleet Leadership" or "Player Administrators". If you are allied with a minor faction then you can pledge to the minor faction. If your rep drops then you lose the tag. Minor Faction Tags don't have to be limited to PMFs. Players should be able to pledge to any minor faction, player or NPC, simply by virtue of reputation with a limit of one minor faction per player at any one time. The benefit would be that other players in the same group would see you marked as a friendly in their HUD. Other benefits could be price breaks in the Minor Faction's starports and reduced harassment from the police (i.e. fewer cargo scans, etc.) The label itself does not HAVE to be visible to other players so you don't instantly become a target to other players (though I personally wouldn't mind a visible tag.)
