As it says in the rules, no special skins required.
And there is no point to count the sign ups, there is a table already with all the drivers for which the link is also posted in the first post. So, 70 sign ups to be precise.

New rules have been added (READ THE RULE BOOK IN ORDER TO NOT GET A PENALTY/DISQUALIFICATION):

1. Rule VIII - There will be success ballast for the season to even up the drivers and the cars. (Just to be clear with everyone, don't start arguing about this here in forum. Nobody is forced to drive if they don't want to or don't like the rules, this is my final decision for now, if it will be changed, I'll let you know.)
2. Rule IX - Other penalties in case of not filling in a proper sign up form before the event (only for those who are participating in the event).
3. Rule X - Points system: Nation points.
4. Rule IV - General rule. Point 5. - Short cutting.

Choose another number, please. That one has already been taken by the guy 2 posts above yours.

ok, sorry, just the next number on your list will do then.

Your number will be 39 then, since that is the next free number. But edit your sign-up post just to not cause any confusion if future for me.
