I'd like to see some kind of item that you could use to make the limit to the number of friends/guildmates increase.

Kind of like the backpack extender in TF2, but for players. You'd buy it for like 50K Cr/1000 ce, or some price set by OOO, and then use it- you could then friend another 100ish people (and have 350 friends, rather than a lowly 250), or use it and make it so that your guild could consist of 200 rather than 100 people. This would make a nice sink for energy or crowns or whatever is needed, and would make for bigger guilds of people, and would help to not have to kick people from your lists. I would buy one.
