Recently, I did a website where we had to set up membership. I found a plugin so I could customize a login page with their logo. WP-Customize was easy to use and did the trick. You can see the login page if you try to register at the site: http://www.testycopyeditors.org.
I also learned a lot about setting up membership, user roles and managing members. Lots of good plugins for these types of sites. Here is the before and after:
Some good plugins to consider:
- Custom roles for author
- User Switching
- Replace Howdy with Welcome
- Email users
- Add multiple users
- WP Hide Dashboard
