I just want to clarify this
1. I don't mean to offend anybody, maybe I sound like some bender but I like Jiu Jitsu, I want to train with everybody and I want everybody to reach their potential...the better my training partners are the better I get, the better my opponents are the better I have to get! So I think that if you want to contribute to the community do so in a way that's because you want to improve the sport not to try and make some easy money, If we try and scam money out of each other the sport will never grow but if we help each other we're all going to improve
2. Spartan is a massive facility and could hold plenty of people and it would be a great day which I would have a great interest in attending
Also I don't want anyone to think that all the RJJ boyz are hopping into the thread to piss people off or trying to compete with Spartan, if you want to make money off of this do so but I think it's fairer to do it for the sport and not for profit, if you want to profit teach classes. It's only fair that people know how an open mat works.
It's too easy to make money off people who don't know better and I assume that the OP didn't understand that the point of an Open Mat is for people to train together not for profit
