Advice; About Pages vs Rules Pages
An about page is where you describe information about your muse. It allows potential writing partners to see who they are and decide if they're interested in writing with them. An about page should ideally consist of the following:
Basic bio information (name, age, etc)
A short physical description (this is useful even if you have a fc image because you can describe how they may differ from the image!)
A short paragraph describing what they're like as a person
Any relevant history information
Of course, the more information the better, so you could write more than this if you wanted to! If you have a really long about page, having a short, condensed paragraph summary at the top of the page is a good idea.
An about page is also a good place to put any AUs you may have for your muse (or you could create a separate verses page!). For AU information, you should describe how your muse is different from their main verse.
You need an about page if you are writing an OC. Your OC is an original character, so you need to give potential writing partners that information so they can see what your OC is like. If your muse is canon divergent or AU based, you should also have an about page because people will want to know how your muse differs from canon before deciding to write with you.
If your muse is a canon character, you should still consider having an about page. This is because you're likely to have headcanons that differ from canon, so writing them down prevents confusion later on. It also allows people who aren't familiar with the character to learn about them so they can write with you too - this is especially important if you write for a small fandom!
If you're a new blog, writing about pages also demonstrates your writing ability and style, which can help you get your first interactions!
If you're struggling to write an about page, I have prompts for basic character information here.
A rules page is where you write the rules for writing with you. Common rules are:
No godmodding (controlling your writing partner's character)
The length of replies you want to write
Any topics you don't want to write
Some people also include a brief description of themselves here. It is a good idea to include whether you are under 18, 18+ or 21+ as many people have age restrictions in their rules.
Making a rules page is important because it allows you to set restrictions that potential writing partners can check before interacting with you. It also allows potential writing partners to check that you are compatible with them.
It's important to read a partner's rule page before interacting with them. It's surprisingly easy to tell if somebody hasn't read your rules, and people are unlikely to want to write with somebody who hasn't read them.
