The best way to get started in roleplaying on EcchiDreams, is to fill out a Roleplayers Preferences Sheet. If you're not sure on how to do it, then there is an easy to understand guide that we wrote on how to set up your own preferences sheet. This sheet lets other roleplayers see what you prefer when it comes to roleplay, such as doing sex only, or not interested in impregnation roleplays.
Next, you might want to decide if you're interested in doing Private, or more Public Roleplaying. Go for what you think is best for your own style. I would advise that you take a look at this etiquette guide which advises you on how to treat your fellow roleplayers both in, and our of roleplay.
We have an ultimate guide on how to start roleplaying, especially for a beginner. It is called the Crash Course in Roleplaying, and gives a lot of hints and tips for roleplayers, both new and old and contains all the information you need.
If you are new to setting up your own roleplay, then we also have a Game Master's guide which can be useful for both new Game Masters, and old. It details out all the things you should consider while setting up a roleplay, especially if it is complicated.
