As a alumnus of the GO-GN network, I was fortunate recently to be able to take part in their Wiki Scholars programme.
I had some experience of editing Wikipedia a bit before, but it was a long time ago, and the interface has much improved since then (about 12 years ago I think!). As well as showing us the technical nuts-and-bolts of how to contribute to Wikipedia, Will, our instructor, also showed us a fascinating range of tools that can be used to explore the content on Wikipedia in more detail. Lots of inspiration for things to dig into and follow up on!
The course took placed in one-hour sessions over several weeks, and I would highly recommend it. Also, it was lovely to see fellow GO-GNers again too 🙂
