So far, the 3 main rules of modding are:
1- You CANNOT allow online cheating
(only people with the SAME mod should be able to join the server.
Making a mod that allows you to mod in a 'stock' server is baaaaad)
2- You CANNOT edit the body meshes (or tracks) in any way.
The only exception here is the mags. Apps like BeSpoke are tolerated.
3- You CANNOT allow HotLaps to be uploaded to LFSworld.
(This is where MecaniK has failed miserably...)
Anyone taking advantage of any vulnerabilities and caught cheating will
be punished, possibly banned from online racing completely. Also, there
are good chances you'll be banned from any LFS 'services' like LFSWorld
and this very forum. I'd take this very seriously if i were you. As long as
you show good intentions and respect these basic rules, there are no
reasons to reject the app/mod.
Btw, you can send those mods to me, i'm usually the person who is
called on to verify these kind of things, usually...
