Reaching out, and a quick question

Hi! *waves*

The community is so small on here I really want to talk to everyone and make new friends. But... I'm shy ;_;

I love the blue design, though. It's my favourite colour. Clearly I belong here. /cough

Seriously though I'm so happy someone would consider inviting me here~ Thanks Tia ^u^

Okay so I have a question:

So... What we put on here, is it all required to be based off something or other~ or can completely original stories be posted? New worlds, new characters, new everything? But I guess that wouldn't be fanfiction... just, fiction.

I know it's a completely stupid question but I had to ask it. :/ I promise I'm not usually this dumb OTL
