A few of your other points:
Cosmetic items can be added, but we struggle with models considering there's very few people capable of actually making these -
@Madda seems to be improving on this front so maybe he'd be willing to make a few now and again.
There's little to no cars left in the TDMCars pack that we can use, we added the rest (with the help of
@D3V) a few months ago. The only way we could potentially add more cars, is if we used another pack such as the Wolfie ones. This is a possibility and
@TinySlayer and I played about with the idea, however it would likely require
a lot of work.
New in-game content is in the works, and I will personally be releasing as much as I can after Christmas - I really would like to address the primary concerns of all players and then work toward more cosmetic, smaller things. It's important that we get the main gameplay mechanics sorted before we think of completing less-complex tasks.
I can't speak for the actual process of staff complaints anymore, but I doubt it has changed in the last few months - The staff complaints section is relatively straight forward, if you have evidence of a staff member doing something wrong, post it in this section along with some details and Senior Administration will deal with it. I don't see what is difficult or time consuming about this process, if you could suggest ways this actually could be improved, maybe
@TinySlayer @Bolli and
@Madda could take this on board.
@Collier isn't Senior Administrator although could be one day, I am sure he is more than capable to take on this role if the opportunity arose.
