A Chapter is a sub-division of a Lodge. Many lodges are divided into chapters based on how the respective council is divided into districts.
A team, which is also a group within a Lodge, would be appropriately included in this category.
OA Chapter websites and Team websites (dance or ceremony for example) teams are appropriate here. Sites which cover multiple chapters or teams would be more appropriate in the lodge category.
Please include your chapter name (or team name/type), lodge name and number, council name and number and a brief description of your site.
