Inmates pay $50 per year to display their profile and photo, which the public may access for free. The website invites users to write directly to detainees or to send a first letter via its free e-mail forwarding service. Detainees can also apply for a phone call once a week for 30 minutes at a time. Writing prisoners is an expensive occupation. The Guardian has estimated that it costs £50,000 to £100,000 ($66,542-$133,286) to keep one person in prison. This includes hiring staff and contractors to manage the logistics of sending and receiving letters, as well as the cost of materials such as paper, ink, and postage. Prison writing takes up a large amount of time. The average daily quota for registered writers is 16 hours, although this varies depending on the facility. In addition to writing letters, inmates are expected to work on educational programs, journal articles, and other assignments. In some cases, inmates may be paid for their work. For example, some facilities operate a "writing program" in which they hire outside consultants to help them develop new stories or memoirs by famous people. The consulting firm will then assign the task out to selected participants. However, many facilities cannot afford to pay inmates, so they rely on charitable donations from organizations like the Howard G. Bressler Foundation.
