Will try to find users within the sport, going to sport clubs and manually signing up people, shops, online forums, it’s a niche sport with a cool community around it and I’m a player. Thanks for this, the html site with manual ‘back end’ is an excellent suggestion, I wonder if not more work than adapting one of the wordpress airbnb clone themes, that comes with post, calendar and messages plugin?
