First of all, let me express my Thanks and appreciation for all the members who have responded and contributed to this discussion. It helps illustrate the value of this PSR Tutorial forum community.
Second, let me assure everyone that I have paid the bill and we are good to go for another year. That bill, by the way, included not only the server itself, but technical management and support to take care of the software and updates needed to just keep servers up and running as well as other associated fees like domain name registration etc.
As mikf has suggested, paying the bill was not so much about the cost as about the decision to sign on for another year. This thread confirms that there are many people who appreciate the PSR Tutorial and would like to have it continue, more or less as is but with minor changes that may reduce upkeep and maintenance, which, for Roger and myself, is measured in hours not in dollars.
When the forum started, I looked for a way to generate income to cover financial costs. Providing CDs or resources seemed to be the answer. When someone ordered a CD, they became a "Supporter" in the forum -- for Life -- and had access to a wider array of forum resources. So, instead of paying, say $5/year, a purchase of $25 would provide access not for 5 years, but for life. Over the years, thanks to the generosity of many forum members, I have been able to collect and create new resources every year or so. You will notice many users have the term "Supporter" next to their name, meaning they have, at some time, provided support by ordering a data collection or making a donation. Others may have "PSR Performer" by their name meaning they have provided support by contributing their music to the PSR Tutorial. Some members are shown as "Senior Members" meaning they have shown their support by providing answers and comments in the forum on a regular basis.
There are donation buttons on the main web site as well as buttons to order any of the available data collections. That has worked and, I assume, will continue to work in 2022 as long as the main site is still there and maintained. The forum remains free and open to the public (just as the web site is free and open to everyone). In fact, most of the things provided in the various "collections" are available on the main website and can be freely downloaded from there. If the main site disappeared, we could switch the forum to some kind of subscription basis but no need to do that just now.
Fortunately, over time new Yamaha keyboards worked pretty much like earlier keyboards so most of the lesson material remained relevant. I've tried to supplement some lessons by using the screen shots from the new SX900 where the user interface is a bit different from earlier models.
I'm not so sure how valuable the coverage of MP3s are. Over the years, I have received over 8,600 MP3s. 4,800 are still available online. What to modify here may be a separate discussion.
In the meantime, the PSR Tutorial and the forum will continue through 2022. Maybe this will be the year Yamaha releases the next generation and we will have plenty of new things to talk about.
