i have made a wikipedia article once on the dutch wikipedia,[citation needed] but it was much tougher than I expected.(correct sources, also many non-primary sources are important). Nowadays I usually make small edits. Also I noted that quality from page to page can differ greatly.
also usually when i donate to the internet archive i wait until mid december, the last few years they had 1:2 donation matching, no guarantees for the future of course but if they won't have that I'll just donate then regardless
just changing stuff so it works better on small screens, no actual updates
