@Matthew-Price and I have just recently launched NodeBB for a customer of ours who specialises in Japanese Raw Denim. They've been using SMF (plus Tapatalk) since 2009 and we've successfully migrated all of their posts and users into NodeBB.
The theme is a modified version of Persona that we've customised to suit their branding, as well as some tweaks based on feedback from the customer and their customers.
Many thanks to the NodeBB team for the great forum software as well as the contributions and plugins by others, it has been positively received and a welcome change from SMF

@bh4-tech we're in the same position. We trialled ntfy and it isn't great for those that aren't tech savvy.
Users want a one-stop shop and the most painless experience.
We're being pushed by the fans over at Iron Heart for a solution so we're keeping a careful eye on progress here.

Nice update PitaJ!
One small issue I've encountered; I have a forum where the URL is not at the base level (the client wanted to retain it like so due to many years of indexing) and so therefore the API call within settings fails due to it referencing '/api' as an absolute URL.
I've raised an issue on GitHub: https://github.com/pitaj/nodebb-plugin-calendar/issues/157

Ah, I clearly didn't look hard enough! (was in between tasks!)
Thanks for confirming.
