How is the order of the rooms list determined.

Currently the rooms are listed by most number of users by default. This is to move rooms with 0 users to the bottom of the list making the rooms near the top more relavant. In the past the rooms were listed by alphabetical order. This option is still available. There are several options for re-ordering the lists. You can use the dropdown menu to order by room type ie: Buzzen official rooms, Buzzen supported room, or User created rooms. You can also order the list by alphabetical order, or language. To do this you will need to click on the Header name. ie: Room name, Users, or Language. If you are having a hard time finding a room you can use the Search page located @ https://www.buzzen.com/searchrooms.html
