So I bought FoG last night, and I was looking at the online challenges available, and it had a whole bunch of them listed with locks on them. I believe private challenges? The accept button appeared to be active for them, and I did not want to accept a challenge due to having no clue about the rules and strategy yet. So what's up with the games with locks on them?

Welcome. You're right, they are private challenges and protected with a password.
If you want to play without setting a game up with someone you have to look for open challenges.
They tend to be picked up quickly though so the best option to get a game is to post an open challenge yourself.

Thanks, not yet ready for challenges
