I just received the upgrade notice. I have been using Fences for a couple years now and enjoy it. So no problem with the upgrade. But I am curious about the trial time. How long is the trial? If I decide that I do not want the new version can I revert back to version 1 without cost? How do I do an upgrade? Do I need to remove V1 before installing V2? That would loose all of my current Fences, which would make the upgrade unacceptable.
