"Open challenges to race against each other can be done in PM, but feel free to post it up here when the race is done.
Open challenges to anybody in a particular area is acceptable, as long as there is no flames, and all subsequent acceptance/correspondence is handled in PM."
Uhmm, You might want to add "At the track" so AF wont be fined liable when some kid runs into another car and kills himself or another.
Edited some out cause I reread it. All in all, people if youre going to call someone out or accept a challenge... THINK and dont POST the location where its going to be, the date its going to happen and DONT give any hints out to where it might be going on. Like Carrrnut said, handle it through PM.
