Hi there!
It's important to introduce yourself before starting to post. That's a rule on every single forum on the internet.
BUT sometimes, people just like to remain anonymous and just RP as their character, and we'll respect that.
So what we will ask here, is just to make a post to say hello, even if you directly say hello as your character.
This is more a way to see than you are not a Bot or a kid who can't write properly, than a way of spying who you are.
So yep, as long as your post is a bit longer than 5 words, you really don't have to speak about your real self.
Hey it's a roleplay forum, not a dating website, so who cares if you're a boy, girl, dog, as long as you're a Mario fan!
Also you can activate your roleplay sheet here, it helps a lot :
