Worlds marked with a green bar represent normal Worlds in which you can chat with users. The green can change from orange to red, to indicate the amount of room left in the World (ie: full Worlds will be entirely red).

Worlds marked with blue offer special activities such as Draw It!, and the ability to watch videos.

If you are having trouble accessing the World, you may want to try clearing your cache, which could be conflicting with the loading of the World location. As well, if the World location is full or you have been banned from accessing the World, this can also affect your ability to get in.

Alternatively, you could try using a different web browser, or try again later.

If the problem persists, contact WeeWorld.
