The criterion for inclusion here is that the parish (or church) website should be active - kept more-or-less up to date - preferably by inclusion of a current or very recent newsletter. Parish websites which show no sign of anyone keeping them maintained have been excluded. If your parish has an up-to-date website and isn't listed here - please tell the webmaster !
