I love editing Wikipedia pages and wanted to showcase my Wikipedia contributions quickly on any of my sites that are using WordPress, so i developed a Wikipedia user contributions plugin. Results for my username are displayed below. I believe it has a Github—yup, it’s right here.
Super barebones, current version is set to show just my contributions, but if you fork it, simply edit the main php file, swapping out the username variable. One day i’ll augment and polish this plugin with styling options and other bells and whistles. At least i made it print out via a [shortcode].
Just updated it (2017.10.16) to have a barebones Options page that takes the username you’d like to display. I’ll update the repo now. And hope to increase the offered options in the near future. Cheers!
