Abstract: A system and method of providing internet services to sports enthusiasts such as tennis players. According to the method, an electronic communication from a tennis player is transmitted over the internet to a virtual tennis center web site which determines whether the tennis player is an authorized user of the web site. A password prompt can be displayed to allow the authorized user to obtain full access to various screens on the web site. The web site determines whether the electronic communication is an e-mail or search request and conducts a search in a searchable database if the electronic communication is a search request. Alternatively, a notification is sent to one or more authorized users of the web site if the electronic communication is an e-mail intended for the one or more authorized users or a notification is forwarded to one or more authorized business entities if the electronic communication is an e-mail inquiring about tennis goods and/or services.
