something to earn money with for you guys:
Add a message window. Allow players to send sms messages there. May include recruitment ads, or just mocking ppl
every sms should get you some money. Could also be used for announcements.
Also take the game feed to the interface itself like the so often mentioned news feed. Don't hide every feature behind 2-3 clicks, make them visible all time.
I've seen this in other browser based games and I repeat it adds much to the immersion. The sms function is also a great way to pick fights and gives multihunters something else to do than closing planets for wrong fleetnames
