Oh, I didn’t know we cost so much i.e. I for example have enabled desktop notifications for all 3 forums. Sorry 
But honestly … I didn’t heard about costs when last time I was dealing with them, but things change and my information does not have to be up-to-date. 
Or just post on forum and let people know there is a forum setting for enabling a desktop notifications. 
@bartblast Hmm … I’ve got all your points, but the forum allows you to do all of that absolutely for free and literally without any work from your side. People can enable push notifications or emails in their own preferences page, for example here is one option that 100% match your case:
Email me when I am quoted, replied to, my @username is mentioned, or when there is new activity in my watched categories, tags or topics
All people have to do is to just watch the specific topic. 
Of course you may post directly on the forum or just post the quoted summary and simply add a link to your page. Please keep in mind that the community here is rapidly evolving (see changes to library updates). Also I would think about one more things i.e. views. There is much bigger chance that you will have more clicks by cross-posting or posting summary on the forum, so in my opinion posting (this or other way) here is best in long term. 
Unfortunately I prefer to not share my email too much. One time I’ve got lesson when my email was exposed and I will rather follow my rules:
Of course it’s your decision. If it’s not best for you it’s fine. Hope you would have a lot of subscribers as you anyway do an amazing work.
