To start a new gallery, you need to add a "/" on the episode page, and "Gallery".
Galleries should have no borders and should be in the "center" position. When adding images make sure "File:" goes in front of each image name.
Make sure the galleries you added have a "Galleries" category, so readers can be directed to the list of galleries that were made.
After a list of characters on the episode page, some are followed by either, "(does not speak)", "(cameo)", "(mentioned)", or "(not seen)". A "cameo" appearance is a minor appearance where a character is seen, but doesn't speak nor is it referred to. A "does not speak" role is where a character appears and is referred to by name by either the narrator or another character. When a character does not physically appear, but is mentioned by a character or the narrator, that is classified as a "mentioned" role. The "not seen" tag is most often used for books. This is when a character speaks, but isn't seen in any of the illustrations. A speaking role is, obviously, when a character actually speaks. Anything that requires a voice actor is generally viewed as a speaking role, however there are some exceptions to this rule (If someone is talking in the background). If any other confusions occur, please notify an admin or leave a message to the relevant talk pages.
The explanation section is for explain readers on certain things the characters might mean. (eg. Crow's feet are wrinkles on the corner of eye.)
The trivia section is strictly for unique information about the episode. This may include fun facts about episode production, character's debut, or anything in particular. (eg. The Esther episode was originally planned to be released on Spring 2001, but was pushed to Fall 2000 instead).
Remarks This sections is strictly for remarks, where sometimes the continuity might be off from before.
This is strictly for any production mistakes.
Usually in shows, they might often make a small callback from a previous episode, or a prop or location from another.
However, the main thing you need to make sure that your edits is that they need to be reilable, because we want to truth, not lies!
