Abstract: Method for exchanging permissible information between a sender and recipient that are connected to a data network through a hosting website. Textual information is exchanged between the sender and recipient using an accessible electronic dictionary that contains a set of permissible words, excluding combinations of characters that are not permitted by the hosting website. An algorithm may also be used to exclude words under certain circumstances. When a message is composed by the sender and sent to a recipient, it is first redirected to the hosting website. Only when this has verified that the words used appear in the dictionary of permissible words, is it directed to the recipient. Otherwise, the outgoing message is rejected and the sender notified that the message comprises non-permissible words. When permitted by the website, for example after a payment is received, the sender and recipient are allowed to exchange messages using any words.
