Where do I find things in Members?

The left menu holds Home, Members, Renewals, Dues & invoices, Groups, Events, Communications and Reports, with Organization Settings and Help & guides pinned at the bottom.

The left menu:

Home — your dashboard, and Needs you today. View all tasks opens the full task list.
Members — every member. The Membership cards button at the top opens the cards page.
Renewals — the renewal work queue. The Review queue button opens renewal answers waiting for a person.
Dues & invoices — what is owed and what has been paid.
Events — events, registrations, check-in and continuing-education credits.
Groups, Communications and Reports — these sections have not been built yet and show a placeholder page. Renewal notices are set up in Organization Settings.

Pinned at the bottom:

Organization Settings — Org admins only. It has Membership levels, Terms & renewal rules, Renewal notices, Renewal questions, Membership card, Users & roles, Sign-in & security, Active sessions and Audit log.
Help & guides.

Your name at the top right opens a menu with Your devices and Sign out. If you belong to more than one organization, it also has Your organizations, and you can switch organization by clicking your organization's name at the top of the left menu.
