Abstract: This invention is directed toward an internet-based, interactive wedding planning and management program which allows a wedding group, including the brides, grooms, guest, and wedding planner to interactively plan the wedding, where the bride is the primary account owner and can give each invited guest different usernames and passwords, along with the ability to give administrative access to others, such as a wedding planner, and can set up “user” access limitations which denies information to certain people regarding sensitive features of the wedding. The bride and her administrative users can assign tasks to various guests, which the invention tracks through to their completion. The invention also provides online and interactive features to assist in wedding planning and management, including budget calculators, wedding item organizers, task lists, calendar functions, guest manager functions, a message center & community chat, printing managers, wedding day schedulers, and a wedding checklist.
