Yup, hima's right. The judges need an unencrypted version, but you can also submit an encrypted version for the community to download.
Right now, it's 4 am on the morning of the first. The deadline was set to be at midnight tonight. There's a good chance that I won't be around tonight, though, and if that's the case, you guys have an extra day to finalize things, zip them up and submit them. The deadline will officially be whenever I come online and check my PMs after tonight at midnight, essentially being the first time I check my messages on the second.
