What do canon and non-canon mean?
These are standard terms for describing what’s officially a part of the story and what isn’t. Characters, actions, and events that are officially a part of the Wotch, as determined by Anne and Robin, are considered canon; and everything else that might happen, or might be discussed in the forum or written about or drawn in fan-created works is considered non-canon unless Anne and Robin say otherwise. So, for example, all of Cheer! is considered canon within the Wotch because Anne and Robin declared it so, even though it’s drawn by Tselsebar and not Anne or Robin; while “Wotch the Time” is not considered canon (and is considered filler) despite being drawn by Anne and posted as a comic.
