I am building a site for a youth sports organization. They would like to be able to take registrations and payments online when a child signs up for a particular sport. For example someone registers their child for baseball for the fall season and pays online. Could someone suggest the best option for this? I've looked around but this is the first time I've ever done something like this and I'm not sure what is best suited for it (maybe the Events Registration plugin?, can wp e-commerce do this?, other). Any help is appreciated - thank you.
