It is the result of more tan 20 years experience in the world of sport all put into a single platform, offering a whole new tool for Sporting community. WSSN is for athletes, or for people who want to play or do sport; with this social network they can look for and find other people they will be able to compete or train with, assemble teams, find competitions to take part in, etc. It is also a very useful tool for Sports facilities, as it helps them to manage the reservation and booking of tracks and playing fields… and gives them a way to easily communicate with their users. Competition and Championship organisers will also find this tool very useful as it will help them to find people interested in taking part, help them to manage the competition in a whole, offering the possibility of online registrations, publishing results, scores and rankings in real-time…WSSN brings people together and puts them into contact with others of the same interests.
