Hi Ben…the amount of seclusion from the outside world varies. In women’s enclosed communities the nuns do come in contact with “the world” in the parlour through visitors and most communities allow friends and/or family members. Most enclosed communities stipulate how many times a nun may have parlour visits and the most common I think is one parlour visit per month. Some Orders stipulate only family or friends - one or the other…other Orders make no stipulations about who, but they may stipulate how many people can visit on the one visit.
Orders that have very strict enclosure often have what is known as Lay Sisters who are nuns in every respect except they may not be members of the ‘choir’ per se. These Lay Sisters go out an do the shopping and often most of the manual work as well.
Some Orders may have friends who collect the shopping list and do the shopping for them. Some allow two nuns usually who do go out and do the shopping etc.
Nuns nowadays do go out to the dentist or doctor. Once upon a time (and I dont think this exists any longer) the dentist and doctor would come into the enclosure. The nuns had a black see through veil that they would use to cover their faces if an outsider of any kind was within the enclosure for some reason.
Nowadays I dont think there is any restrictions about having an electrician or plumber inside the cloister if this is needed. I am unsure, some Orders may still retain the see through black veil custom of covering their faces.
Contact with other members of their Order used to be by circular say once monthly or on special occasions…nowadays of course most Orders have a computer and keep contact by email. Some Orders may not have a computer, nor want one, and maintain the old custom of circulars.
Members are recruited mainly by word of mouth…although nowadays I notice a lot of enclosed orders (and probably most) do have websites. They may advertise too in their local Catholic newspaper or other Catholic media.
Blessings…Barb

PS I think you may be right, Ben, and the website is no longer up and running!
