We're shutting down this round of strategus on sunday, and a new one will start somewhen in January.
Please drop suggestions what you want changed, keep it short and to the point though.
I'd say plus up the interface as much as possible, less long lists of equipment/numbers at every opportunity and make it simpler and more graphical like Butan's inventory thing.
Add little things to create atmosphere like different optional titles for the owner of a fief besides Lord (Example: Chief, Jarl, Count, Baron, Sir, Caliph, Bishop, etc). If possible connect faction banners to fiefs so instead of just colors maybe they could have the faction's symbol over them on the map as well.
Give factions the ability to show their claims on a map on the website, might help mix things up a bit especially at the beginning of a round.
Add an official diplomacy section on the website so factions can list who their allies and enemies are.
Add a jobs/mercenary type board and buying/selling board on the website. Basically incorporate all strategus related forums into one area so people can find and make use of them.
EDIT: And get rid of out of date stickies on the strategus general info forum.
