Something I threw together as an example of a clan blade:
Obviously my Photoshop skills leave a lot to be desired, but it works as an example as to what would be nice.
The clan chat option would bring up a list of current clan members online and you could send a chat invite to each member you click on. This would require group chat, obviously.
The three boxes underneath would change depending on which three games currently have the most clan members playing, with the number in the corner representing how many players are playing that particular game.
The third, "Manage Clan Roster," would appear the same to each member in the clan, but once clicked would offer different options depending on what rank you currently hold in the clan. For lower ranked members, the only options available might be to "tag" notes onto other clan members, viewable only to you - little notes like "Ghaleon from GAF" or "loves to co-op Gears". For higher ranked members, more options would be available, namely the ability to promote/demote other members.
I'll to get "Browse Community Clan Listings" at the end.
Below that is a clan mailbox, for sending out mass messages to all members, or just messages to members of a certain rank.
"Clan Members Online" is just what it sounds like.
The calendar on the right is editable by all members (or members at or above a certain rank), and it appears the same to all members. It's just an easy way to organize games or to set dates for tournaments or clan matches.
Beneath the calendar is your clan logo - how you could actually import this, I don't know. Maybe you would just be given a small area in which you could "paint" - assign this task to the artist of your clan. And this would obviously fall under the same ToS rules that apply to the Vision camera. To the right of that is your clan name, along with the total member amount and the total number of clan "wins (see below)."
I can't think of any way that the 360 could keep track of "clan matches." Since no games currently have any type of clan functionality, I don't know how easy or hard it would be create a system that can keep track of "official clan matches." It would be nice to be able to pull up the dashboard before a game and enter the opposing clan's name, at which point a notification would appear on that clan leader (or highest ranking member currently online)'s screen signifying that they have a challenge awaiting (this could come up in the clan mailbox, viewable to all, but acceptable only by leader or highest ranking member currently online). At the end of the next game between these two clans, a win or loss would be recorded and issued to each team.
"Browse Community Clan Listings" would bring up a list of all clans on Xbox Live (perhaps all clans that have an "allow public listing" option set). Each clan would have a set of notes attached to it (each of which the clan has the ability to set to private or publicly viewable) - clan motto, clan leader, whether or not the clan is accepting new members, whether or not the clan is accepting challenges, total clan wins/losses, or any other number of cool statistics/information.
As cool as the wins/losses thing would be, I realize that it would probably be impossible to do, since no games currently have clan functionality.
Anyway, just a few ideas that I would love to see. Are you listening, MS? Are you LISTENING?
