Well.....this is the torn forums. So it's not unusual for a torn member to start a thread on the torn forums about a torn race. He just thought is was great that torn had a great rider turn out and was basically congratulating them for that. If tccra would have had a huge number of entries and torn didn't you would have seen this thread on the tccra forums instead. So there is nothing wrong about torn members being proud there was a good turn-out at the first race of the season.
As for you posting about the tccra race this weekend I personally don't see an issue with it but I am 99.9% sure if someone had posted there was a torn race on a tccra off weekend it would be deleted. There has been an issue with someone posting they were having a riding party,no charge, just for funzies posted on the tccra forums but it was deleted because it was in conflict with a tccra race. So now you know the rest of the story.
Good luck!
