Does anyone know how to do this online or does it have to be sent by mail? I can't find anything about it on the website.
When you first login, you should be on the correct page. You'll see three different tabs. You want to click on "Challenge Information" tab, and from there, you'll see 15 different steps that need to be completed in order to submit it online. Just follow those steps and press "Save and Continue" when you're finished with the step. Or, you can download the form and do it by mail.
Apparently it doesn't show that I ever officailly entered the challenge even though I was getting the weekly emails from BFL. It won't let me click on the Challenge Information tab, and it doesn't show that I have a challenge at all on my dashboard. What do I do now?
Go ahead and enter and use your 1/28 entry date and the complete the challenge form (15 parts as MJelly states). Once you have uploaded your before and after shots, it will let you submit and you will get immediate confirmation that your packet has been submitted.
