1: FCs, or "Face Claims," are pictures used to represent characters. Some writers find it easier or more effective to provide a picture of an actor, anime character, or random person in place of or in addition to a written description of their character's appearance.
1.5: It is by no means required by the website at large. It's a popular development within the roleplaying community, here and otherwise. While I do not personally support its use or the philosophy behind most of its applications, it is the decision of the GM (Game Master; owner of an RP) what is and is not required to join. If an RP mandates a FC be included in your character, it is by that roleplay's owner's discretion. If it is something you do not wish to do, you are free to look for other RPs.
2: This thread is dedicated to helping new members that are looking for help specifically with character, world, and roleplay development, it's not really a general help thread. I'm glad I could be of service, but it would be easier and more appropriate to communicate by private message. I addressed the important parts that the entirety of the community should know, but as far as website navigation and the process of
joining roleplays, it would be much easier to use PMs. It is also possible to ask for help in the
general chat.
