Note: User created rooms are only available as long as they have at least one active user. Empty rooms are automatically removed after 5 minutes. User created rooms also reset after server restarts. If you would like a permanent room that does not reset please visit here.
Room name can't have following characters:
comma (ascii 44), colon (acii 58), ascii characters from 0 to 31, and 127. Space is the separator so it is obviously not included, for space \b is used.
