Any sites that relate to local groups in the UK belong here. If your site is UK based but is about the Christadelphians in general please submit it to the main Christadelphian category.
Local groups of Christadelphians, such as individual ecclesias (ecclesia essentially means church) and other organisations, such as CYCs.
Some organizations have their addresses on the sites of other geographically close groups. If you can't find what you are looking for, try a group close by.
There will be very few, or no, sites suitable for listing in this level of the directory. As far as possible all 'local' sites should be in one of the subcategories of this category.
