October Novel Prep Challenge

Okay, so I'm a newbie to this challenge so sorry if I'm asking some totally stupid questions. First of all, I know that I probably won't have internet access from Friday the 12th until Monday the 15th. Since I won't be able to post in the forum, does that mean I won't be eligible for the grand prize? Or could I do the assignments early and post on the forum, or do them and post later that I completed them?

I still didn't decide what idea I'm going to use for this, I have so many rolling around in my brain. So I made a kinda rough poll that I'd really appreciate if you could take the time to vote for the idea you like best. Here's the link: "Invalid Item"  Thanks guys!
