 * Dear Nythar,
 * I've received a message from you asking me not to vandalise Wikipedia. I'm confused by this because, although I consult the site regularly, I am not a contributor and have never knowingly edited any of the articles there. It is within the bounds of possibility that I may have inadvertently clicked on something and caused an issue, but any alterations or vandalism I may have committed were made in error, without me even noticing.
 * I apologise for any inconvenience this may have caused. Perhaps if you explain the edit I appear to have made, I can try to avoid causing you or your colleagues any more headaches.
 * Thank you,
 * Joseph Young 139.80.172.131 (talk) 02:43, 22 May 2022 (UTC)
