@Catija Well, this was also a bit of a weakness from me, since I realized to late, that the decades thing wasn't really too big a matter and her approach wasn't too bad (and I was glad she followed it through). So I couldn't just say "yeah, you're absolutely right, I was making a fuss out of nothing", so I chose a rather spiteful approach to that. Might not have been the best situation at all. She definitely wasn't acting very appropriate, but I also didn't handle it in the best way possible
But I feel we (and I) have failed if we drive a user away, so I tend to try to please everyone. We had an intance of a very contributive user driven completely away by a stupid rollback war. And I'm talking about one of the most prolific editors ever, who asked and answered many questions and also contributed on meta. And that for two years since the site started. And that stupid incident let him to completely abandon the site. And that was definitely a loss.
