Summarize this article:

Search for something like “Harry Potter roleplaying sites” or "adventure roleplaying sites" to get started. Make your selection based on personal preference of the website and discussion format. Search for genres such as action, mystery, crime, drama, and romance.  Popular roleplaying sites include https://www.roleplay.me, https://www.rpnation.com, and https://www.role-player.net. There are many roleplaying sites catered to specific interests, such as Dungeons and Dragons, Star Wars, and other movies, video games, TV shows, and animes. Pick a topic you genuinely love so you can easily get into character. If you aren’t very passionate about the topic, it will show in your dialogue. Most roleplaying sites offer either instant messenger, chat room, or forum threads to communicate with. As you browse roleplaying websites, make your decision based on what kind of formatting you like best.  For example, you can use a forum set up on www.roleplay.me to act out Harry Potter characters. Instant messaging roleplay sessions are more private than public forum sites. When you make your decision, look for a “sign up” link on the website you choose. Type in your name, username, email, password, gender, birthday, state, and country. Then, click on “sign up” when you complete all required fields. In most cases, it is free to sign up for a roleplaying site. After you’ve created an account, browse through the people, forums, and blogs to find a partner looking to roleplay. Read over other users’ accounts to get a sense of what they like to roleplay, and make your decision based on personal preference and experience level. Then, message the user or reply with a comment to see if they want to roleplay with you!  If you are just starting out, it is helpful to pick an experienced and patient partner. You can play with 1 or more partners, and you can join an existing roleplay session if you'd like. Simply message the users to see if you can join!
