Hello! This is ThatJakeGuy. Ordering a room is quite simple. You can order in the lobby or the front page. I will basically take your order for how you want your room to look like. (e.g. next to an ocean, mountain view, etc.) It doesn't stop there, however. You can request certain ITEMS to appear in your room. (e.g. a sprite from a game) As well as your avatar, which will appear on the bed. Don't expect your room to be done immidiatley.
When you have a room, it's a place you can share your things! You could share your art, or a project you're working on. It's basically a page about you. You CAN share projects/art in the lobby tho. Hope I have helped!
