@ToshibaSaoyiWelcome ToshibaSaoyi to the guild! As it is a Role Playing Guild, then either you have interest in becoming a Role Player or are or have had previous RP experience. The first thing I did when I first got into Role Playing, was that I found what I thoroughly enjoyed writing about. Being a writer of Horror and Fantasy, it wasn't too hard for me to figure out what I enjoyed to RP about.
If you aren't sure what you want to RP, try out anything that sounds interesting. Start by checking out the Free Interest Checks:
http://www.roleplayerguild.com/forums/12-free-interest-checks. Free Role Play is the easiest form of RP on the site. I say this because all you have to do is really make a couple sentences that belongs to your story and usually Free RP's move along pretty fast. Casual is the next step followed by Advanced. Then there is Arena, 1x1, Nation, and Table Top RP. I'm sure there is something that will catch you eye, be it Star Wars, Hunger Games, Avatar, Dragon Ball Z, Zombie Based, Video Game Based, Romance, Mystery, Fandom, etc.
I absolutely should be the last person posting this, since I suck at explanations, but if you have any questions please ask. I'm sure someone if not myself will have the answer to it. I think that's all I got for you and the welcome party should be along shortly to give you a more in-depth and accurate welcoming! I hope you enjoy your time at the guild!
