I am new to B2Evo and was wondering if its possible to use it to manage all the user auth and permissions with custom pages? I am looking to build my own site but with customized pages for displaying awards for users within my community and syncing my discord server.
I am not sure if there is any type of guide that shows what variables or functions contain the data I would use within my own custom pages.
If you want to create custom pages that are restricted by the user permissions, you can use custom template that you apply to b2evo "standalone pages". Once b2evo has determined the page is allowed to display, the custom template can do whatever it wants.
See the "template name" field here: http://b2evolution.net/man/item-type-general to apply any template to any page.
