German Sim Mod Foundation

Hi.

I'm new to rFactor and mod. A few questions.

1.
Can I add new cars that I made myself through mod in rFactor?
2.
How about track? Can I add race tracks/course I made myself to rFactor through the mod?
3.
To add my own cars and tracks, do I need to get licence from car manufacturers? and if I add a track based on F1 circuit, do I need to get license from them?
4.
If I use the tracks and circuits for my own playing only, do I need to pay licensing fees to anyone?
5.
How easy is it to do mod for rFactor? How many months to make a decent track? How about car? How many months need to make a decent good looking car?

Thank you for any replies. I am really trying to decide if this is something a project I could do for my University...

1. yes
2. yes
3. when you made it FREE for anyone...no
4. no
5. RF is easy to mod in the comparison to other games. how long it take...nobody can say, all people are different in talent/speed/etc. p.s. pcc2007 has take 1 year...and learn how to made it much, much more
