Hi
, adding you and your team to LFSworld is only for info/stats purposes. The addition is not linked with the sim (as far as I know).
You simiply need to make a new driver name (or rename the existing one).
Go to LFS's Options > Driver > Driver Name:
Say for example the existing one is
Kaktus. Just click on it and you can rename it. If you want to make a new driver name, just click on new.
Type in [SIMD] Kaktus (or whatever that you like). You can get colours by pressing CTRL (and clicking to select the colour before you type). Or You can simply press CTRL+1, CTRL+2 etc. to directly select the colour.
Hope that helped.
PS: When I said that LFSWorld team registration is not linked, I meant that I could rename myself to [SIMD] Silver and race online without any issue. It sort of registers your team on LFSWorld, but it wont prohibit others from using the tag...
