I currently use virtualmin gpl, but since I will be rebuilding my server soon, I am thinking of purchasing virtualmin pro. However, I think I need clarification with regards to the license.
When I purchase virtualmin pro, is the license a yearly license that must be renewed each year? Or is it more like Plesk, in that the license is good forever, just that free software upgrades stop after a year?
Since I am only running personal hobby websites, and not conducting any commerce, having this clarified will help me decide whether to stick with gpl, buy a 10 site license each year, or buy one unlimited license every 3-4 years.
