Sorry I only used that over the IRC, I should of edited it before I posted it here. As for Graphics designer, I did this once before for another community, though as simple as it may be we made a pretty sophisticated timeline (of course I plan on a simple one.) that made a poll down the page (the entire thing is a jpeg) and at key points showed areas of events that caused changes to the community over time. Though after four years it died but it was a great place.
The graphics designer would make the timeline in photoshop and I'm using that term very lightly lol.
