After last general meeting, societies (NL: gezelschappen) are now a thing within Thalia. We want to offer some support for these societies on the website. ### One-sentence description A page to list societies on. ### Desired behaviour The page should behave exactly like https://thalia.nu/committees/. A distinction should be made between trial societies and recognized societies, with the trial societies being below the recognized societies under a header 'trial societies'. With this feature also comes society membership, which should behave the same as committee memberships.
