Good to see you Erkka
Damn its good to be back after some years and see a friendly face!
Trust me, Patreon is easy as it gets for end user. I've pushed one blogger into it and it did take him a bit of fiddling around to set it up, bit once its up and running its completely hassle free. In the end, your users will end up with a version of a blog where you post your updates, much like you do on the forum and on a side there will be a list of possible subscription options (you set up the ranges - anything from 1$ to 100$ or more per month), The only thing Patreon is trying to avoid is hot or controversial political debates, but you guys have nothing to worry about there. You might have to pass some kind of screening of course, but again, I am sure that will not be a problem.
And no, you are not THAT old school, not to the point of turning a blind eye to an excellent opportunity to promote your product and make a buck. I know you guys are better than this. If (or rather when:)) you'll decide to give it a try, let me know if you'll need some help setting the thing up and I'll see what can be done.
