An annual printed directory, available only to members, is published in March and an online directory is available year round. Members who wish to travel use the directory or the website to contact the members they would like to be received by. Members are expected to give their prospective hosts some advance notice before making their visit. Last minute requests for accommodation are not appreciated and can simply be denied. Members are expected to answer all requests for accommodation, whether in the affirmative or the negative. Members are expected to limit requests for hospitality to two nights. This protects hosts from being stuck with a guest with whom they are incompatible and protects the traveller from outright refusals of hospitality because of the hosts' fear of that possibility. However, hosts are free to offer longer stays at their discretion - and many do after learning how interesting and pleasant their guests are.
