1. Go to https://www.reddit.com. If you are a member of the community, you will be logged in directly, or you will be required to enter your login details, while a non-member of the Reddit community will need to sign in.
2. Look at the top section of the Reddit homepage and click on create community. By doing so, you will be required to create your SubReddit details such as the theme color, subReddit name, title, description, etc.
3. At this point, you will be able to customize your own subReddit to your taste by adding relevant colors and other important things.
4. Once you are able to create your subReddit details successfully, the next thing is to click on "Create."
This is usually located at the bottom of the form. However, it is important to note that you can only create your subReddit after at least 30 thirty days of being a member of the Reddit community.
