If you have a favorite game, movie or TV show, then we probably have a wiki about it!
And on that wiki, there will be other fans like you who are writing about the topic and sharing their knowledge with all. So just type the name of the game, movie or TV show in to Google, and add "Fandom" to find the wiki you are looking for.
This knowledge base is about the whole of Fandom rather than a single wiki, so going to the community is the best way to get help.
Most wikis have a forum or discussion area where you can ask questions about all aspects of the topic. Look for the link on the right side of the navigation bar. It's just under the wiki's page count. If you have problems finding the forum or discussion area, please let us know.
However, if you are looking for the company that made the game, TV series or movie, we are not them! Fandom's sites are fan-built and fan-run.
This means that they aren't the right place to talk to the topic's creators, or to get help with your game account - but you might be able to find links to their official support sites on the wiki itself or via a Google search.
