While Rob was looking at his user page, one of his friends decided to join Housebill. He sees his "friendUser," which is the username that they chose, among the list of users. The Add a Bill page lets Rob pick a household, pick the users that he wants to bill, set whether this billing amount is in an "exact" form or in the form of a percentage, and then enter the total bill amount. Rob sets the percentages to 50% - 50% for the split between friendUser and himself for the water bill. He puts in the bill amount as $100, and files the category as "Utilities." There is a calendar in the lower right-hand corner that Rob users to set the due date of the bill to the 15th of March, 2011. He does not want the bill to repeat each month, at least not yet, so he finishes his form but clicking on the "Add BIll" button.
