I use football pool version 2.3.8 with WordPress 3.5.1 and it works excellent, thanks for a great plugin.
I just have a question, i have not used Highcharts API from scratch of the World Cup Tournament. Can I start using it now? Will it display data from the tournament's early start and can i delete the file again without the risk of any damage afterwards, as some links will remain eg. or something else? Or if i'm not satisfied with it.
