This looks pretty neat. Two suggestions: show the room list on the home page and put the about stuff somewhere else. People will figure out what the site is by seeing or interacting and the faster they can the better.
Second, names could be more distinct. The fact they all begin with the prefix "user" (from what I saw) is redundant. Could you mix and match from a short-words list to create unique and memorable names? e.g. RedFoxFun.
Realized later this could sound cocky. I meant it instead as a true thanks since coming up with names is hard for me and feels nice to have one appreciated.
