Am I responsible for a Wikipedia article if I wrote it? Some time ago I wrote a few Wikipedia articles covering a rather obscure event I was interested in. I did it more or less completely out of interest and was not paid in any way. Although Wikipedia is fundamentally collaborative, most of the text is mine - the other editors have largely only added results tables, logos, and such.
The organizers of the event noticed the articles and have since been forwarding me requests by a professor saying things like:

You should cite this article. It's good for publicity!
You should write about X, Y and Z. Right now the article doesn't cover them.

However from my point of view, because Wikipedia is fundamentally collaborative, I don't actually own the articles, and if anyone (either the professor or the organizers) want to add those things they are free to do so themselves. That's not to say that the addition will be welcomed - any Wikipedia editor can dispute the addition - but it is something they are free to do. Certainly asking me to do something they can do themselves feels rather improper.
I am wondering if my point of view is reasonable, and if so, how I should communicate with the organizers &amp; professor. I certainly don't want to offend them, since they can make it harder for me to watch the event.
If you think the additions are useful, consider adding them. You thought your time well spent building the pages in the first place, so I would think you probably have some interest in improving them.
If the changes seem to you marginal, or time consuming, write a polite letter to the proposer reminding them that you don't own the page so they are free to improve it. If you're polite and appreciative you probably won't cause offense.
