I have written this page months before, just same as other hosting control panel pages.
But, you deleted the page, with reason "speedy delete"
I even don't know what is "speedy delete"

As I understand, the page deleted because of so called "advertising".
I ask you: is page "http://en.wikipedia.org/wiki/Plesk" not advertising ?

plesk is fully a commercial company, and has no value with respect to an encyclopedia. What is encyclopedic value of plesk version history ?

I advertise your page, on my page, ehcp.net, for months, without asking you anything, I want you to live forever, donated to you,
and you delete this ehcp page with some reason... You can email me, if something is wrong..

I want to write pages with your guidelines and rules, but, give people some chance for learning your rules.. Not everybody can learn all your rules.
