Accounts have a username, an email address, and a password. Accounts may create and administer their own e-cards, or create, edit, or remove (their own) messages on e-cards they have access to. An account has a list of e-cards they own (spear-heading) and a list of e-cards they are participating in.
E-cards have receiver recipient links to send to the card's receiverrecipients, who will view the card. E-cards have a participation link, and messages that participants create and edit. Messages will contain any number of multimedia objects such as text, graphics, audio, and video.
