No problem at all, I got your point!
Only the last one will get 1 or more point.
That's why there is a 30-days limit after the last ring of this chain. After 30 days without valid guesses the chain will be over, will go to the solved section and the last puzzler will have the points. If there will be a wrong guess (a connection already used or somewhat wrong) there will be 24 hours limit to change it or I will subtract a point. This is in order to prevent anyone to shoot in the dark without thinking and this is the reason why I'm not so strict in this (am I Fastka?), when the connection was serious (but wrong\used).
But now, for example, are you going to leave Otto 3 points when you can just add thousands of cars? As time will go by, there will be no more easy connections and if you really want to get points you will have to: look closer to that model, to the manufacturer's history, to what happen in that year, who drove that car, where, why....
I'm only sad because I can't join this chain! But, hey, if someone likes the idea, when this one will be over (if ever)......
