Well, my friends, it really isn't that complicated. Though, if you don't meet the requirements, then you won't get to have your fanfiction on this site.
Step One: Email me!
Step Two: Before you put your fanfic into the e-mail, you need to make sure you have an author's note saying your work is copyrighted material. No one wants there works to get stolen, and this will keep people from doing so. Make sure you put: Ex. This poem, (title), is copyrighted material. Copyright goes to (author)., (first name and last initial, or just 1st name)2002. If you wrote the story, poem, etc. in a different year, then put that year, not 2002. Make sure you put: You may NOT use it without my permission.
Step Three: Be polite. Don't use the copyright in a mean way, just enforce it. This world has too many bad people. Add a thank you at the end of it.
Step Four: Also, NO harsh language as in NO CURSING!! If you do so, you will NOT be permitted to have your FanFic on this site.
Step Five: No sex stuff people, NO inappropriate material, if you do it WILL NOT be put up on this site.
Step Six: Put your fanfiction into the document.
Step Seven: Title the e-mail/subject "Fan Fiction"
Step Eight: Make sure that in the discription of your story, (description NOT required) you do NOT spoil any Two Towers or Return of the Kind info! You may NOT have ANY spoilers in your story either!
Just make sure you follow all of the rules, and you'll be good.
