TasteWP links to spin up a site with a specific plugin or theme
From time to time, I use TasteWP to spin up a site to test a WordPress plugin or theme. It's quite an underrated service, and I hope they are doing good so they can remain in business for years to come.
I discovered that it is possible to preset the installed plugins and themes by using some query arguments. That's pretty handy! This means I don't even have to bother installing the plugin from the plugins screen.
