I found an obscure post that directed me through using the MetadataManager.GetManager(); to add additional columns to the "Subscriber" functionality. Below I have listed my code in a simple form demonstrating what I have done.
Through that post, and a little trial and error, i was able to successfully add the columns to the table, save them from my custom widget into the table, and retrieve the data from the subscriber table to be displayed.
My Problem is that I cannot find any documentation or instructions pointing to how to change the Email Campaigns -> Subscribers -> Edit a Subscriber template, to include my new columns.
I did find a a little information in the "http://www.sitefinity.com/developer-network/videos/developing-in-a-net-cms-should-not-be-a-chore" video around minute 38:15, but I cannot use the Visual Studio Telrick Sitefinity Explorer, Because Sitefinity is installed on a remote server, and my Visual Studio is on my Local development machine.
Can someone point me to how and where I modify this Template?
