You are treading on thin ice here.
First off, I dont think Bergie will appreciate forum members using his resources generously provided to make income. Hobby or not.
I think we all have a desire to see the internet as a cash cow that will open up a new revenue source. You cannot expect me to believe for one second that it will be for the good of the hobby. Besides, a simple google or search will usually turn up the information for free with a little digging.
You really should see the Hobby as a investment for stress-relief and benefits that might give you a better sense of wellness and ability to stay out of the hospital. Not to be used as a revenue source.
Take a look around you and see PDF’s for sale, magazines for sale, information flooding the websites of increasing precision and other means on and off the internet. You cannot expect to successfully sign up more than three or 4 subscribers this way. Even if you did, they will go away once they learn how to get the same information for themselves for free.
Others have said that you can produce material such as magazines, DVD’s Books etc. People have done this successfully in the past, especially when said material meets the needs of the many in sufficient quanity to satisfy commerce and generate some income for the author.
Have at it. But on your own time, and space, not here.
If you feel the need to participate with promoting the hobby with a skill set that is a value to the majority, then it will be your time, expense and effort that makes it happen. Not money or income.
For example there has been recent references to people building small layouts for others to enjoy at Hospitals, schools or retirement facilties. They probably had a sponsor or put up the funding themselves or used what was availible to make it all happen. They dont expect to make a penny out of that labor and expense.
TO see a smile on someone who enjoys the hobby who other wise cannot, is priceless. No amount of income or numb
