I've been using MC for over a year and this is the first time I've had to get help.
I have been trying for hours now with all the resource searches I could think of (Google, this Forum, JRiver Wiki, Bing, etc.) trying to figure out how to simply edit Zone rules after a Zone is created.
It boggles my mind that 'Edit Zone', 'Zone Edit', 'Edit Zone Rules', etc. is nowhere to be found - even in the Wiki. It might be a good idea to create a Wiki page for that - after someone tells me how to do it - or that it "can't be done, you have to delete the old and create a new one". (I have a feeling it's the last.)
At any rate, you would think that infomation was somewhere in the Wiki or this Forum, as I can't be the first one who wants to know the answer. :'(
