You can do WHATEVER you're comfortable with. These contests of mine are very much just for fun and there's not a lot of rules or anything. I only do sign ups really so I have a clue about how many I have to post. :)
Just email me your fic (if that's what you decide to do) OR if you're going to do a poll, email me and we'll coordinate when you should post it. (It's hard for me to post polls that other people have created. I learned that the hard way. lol)
If you want to email me a link to a private journal entry that's fine. I can just copy and paste it.
