Plenty of WordPress communities accept new members. Have you ever wanted to control what happens when your members login or logout? The Login and Logout Redirect Plugin has you covered. It is a lightweight plugin that simply adds login redirect options to Settings > General page.
Simply enter the login and logout page URLs, and this plugin does the rest. Of course you can use other methods to pull it off but this plugin lets you do so without having to deal with NGINX, .htaccess or PHP code.
