Coop Ill be flat out honest it took me a good 6 months to fully understand webmin. Before webmin the only thing I ever used was cPanel. I will agree the difference between cPanel and webmin are night and day.
I haven't had a chance to try Virtualmin pro is supposed to be allot like cPanel. But it also has the cPanel price to go along with it. If I wanted to pay that much I would just buy cPanel.
Webmin may seem a little weird to get use to after using a cPanel server but for $1225.00 the price of a owned cPanel license I am willing to learn.
