I love the bit especially that I've bolded, I mean you could ask each department if they'd want to take part and if they do they can make their own room for it and trade in there all credits will go towards funding for things relating to their departments such as events etc. I just think that Habbox needs funding and they don't have enough to be giving out to lots of credits that we don't have and give them out to departments so we should have a credit shop to help fund big events because going forward we do need something big and not been done before and we can do it but we'd need a little bit of funding for it. Easily do-able in my opinion!
Edit: If any department hasn't got much or anything to give away I'm more than happy to donate a few bits to get it started.
