> It takes effort to dig up some random edit from years ago
Yes, but a simple link to which article it was would be enough. What also might be useful is a user name and/or a rough estimate of what the time period was, but without even an article name, there is nothing anybody can do about fixing these things.
It was a lower tier event or personality of WW1 or WW2. Not a Churchill, Paton or D-Day, but something lesser without reaching insignificant. It was 10 or 15 years ago - in the days when it was still common for articles to be incomplete or missing. I couldn't estimate when that period of Wikipedia ended, but I'd guess at least 10 years+. I'd be amazed if someone hasn't managed to fill the gap since, as articles are generally much more complete. Current Wikipedia has other issues.
It was some hours I spent on a topic I knew well, and had a good selection of books on my own shelves to cite, triggered by finding an incomplete or missing article, or a glaring error. Nothing more. After the challenges contributing I lost interest and moved on. I was doing Wikipedia a favour and trying to contribute, they apparently weren't interested. I'm not going to fight for it, but as a result I'm not open for trying more, or ever again.
As for username, I have no idea whatsoever, but offhand I can only remember one of the several LJ usernames I had, some I used for months rather than just a few days. Mind I doubt I could accurately list all the topics I blogged about on LJ, either, but could cover the main interests easily. I'm not even sure a username was needed at all but it may well have been.
