I started out as a Wikipedia editor in April 2020. It took me a long time to learn my way round this vast system. Now, after four years I have just about got the hang of it although I still don't always do things correctly. As at April 2024, I have made around a thousand edits to some 360 main namespace articles.
As a former journalist and editor, I tend to notice text that needs copy-editing in some way: spelling errors, bad grammar, tautologies or language that simply needs tidying up. I try to correct these when I can. I have also been able to add substantial new material to several articles, and have written a number of articles from scratch.
Waverley Steps. A short documentary film about Edinburgh. If you know the city — and especially if you remember it from the mid 20th century — you'll almost certainly recognise most or all of the places where it was filmed.
