Hello,
Today I've created a new page in sandbox https://en.wikipedia.org/wiki/Webix_JS. I wanted to make it public, but I made a mistake. Instead of choosing the article category and giving it the name "Webix" I've chosen the category User and transferred the rights for the article to not existing user "Webix". That's why I changed the name of article to "Webix JS". But I want it to be named only "Webix". Could you please help me??? Thank you in advance
