Here's a FAQ that may help you:

When are these entries selected?

I will post at random (at the end of the month) day, a topic like this. It are all entries from the month.

How do you can get into it?

If you have a entry that is posted in that month, and get's the top 3 rating, you will be in the list.

How can I be "best JCS'er?

If you have with 1 or more places(for example Single Player) the highest rating of that month.

I hope that this will help you, if you have any questions, I would like to answer them. (no dumb questions please )

P.S Don't watch this topic anymore, I shame of it.
