Shame on me. Found it. I switched between Setups to see the difference. Then the setup is automatically saved.
I just drove some hotlaps an there is somehting to improve:
The fastest Lap for each car on each track should be saved automatically in Hotlap-Sessions.
It would also be great to see if your friends are online right now.
Most online-games provide a buddy-list (if LfS does also i haven't found it till now).
Is it possible to change the user for one LfS Installation on one PC?
I ask this because some friends visit me from time to time for racing. And i don't want them to ruin my statistics!
Another question: Is it possible that more than one PC can connect to LfS from one Internet-Connection? Some games made problems when trying to play with more PCs on one internet-connection. (IP is the same for all PCs?? - Thats how a friend explained me this problem).
