let's start with hosting games with GTP in the title so we can recognize valuable players more easily. I struggle to find decent games as well, and this might help until there's a better way.
I think the Idea of adding GTP to the title of the race would be the best idea. There is no way ive got time to either a) add all those members on the list or b) cross ref who is racing online compared to the list.
Adding GTP to the title would be helpful when selecting races as it will result in a better chance of meeting up with decent and fair drivers but as with GT5P anybody will still be able to take part including the punters.
