Other Character Email The Wheelchair/Portals of Dimensions
From Homestar Runner Fanstuff Wiki
Portals of dimensions were first introuduced in the email dimensions when George and The Wheelchair go to Free Country USA. They are seem to be well known by the characters of both Sweet Cuppin' Cakes and other dimensions, as many characters travel between them. King Snailbert is in charge of the portals, and can shut down the pathway between dimensions at any moment.
Because portals of dimensions are voice-activated, they must be addressed first for a command to them to be picked up. "Portal of dimension" must be said before every command.
