User blog:May304/Entry One

I didn't know that there was a lot of rules and I kinda don't know how the site works. If any of you can help me that will be great. I decided to get an account on here because I often used the site for correct facts so I can write my fanfics without getting yelled at or told that I was wrong. I hope that I can be the best community member I can be. I decided to write a series of short stories but I'm kinda need to ask permission to use some one else's original characters. I can do this right? I'm unsure due to  being new please help.
