I noticed the typo in the change section under Event Operators and wanted to give a quick feedback about it, but I saw it's already fixed in the repo by #21. When I access the WebRef at http://modref.xogeny.com/ it seems like the fix has not found its way onto the site.
And, while reading the feedback section on the site I found another small typo. "with your suggested changed" should probably be "with your suggested changes". I'll send a pull request to fix that.
And thanks for providing the Web Reference, continues to be a great help for me!
