I've never been a fan of the particular forum software used here (I participate in a number of forums around the internet and this is the only place I've ever run across this software). One of the primary benefits of message forums is that they grow into a large body/archive of inforrmation, and good forum software platforms have robust search tools that allow users to easily mine and extract that "group wisdom". This forum's software is really poor at leveraging that particular benefit.
But I've participated in a variety of message forums from the days of Apple ][s and Commodore 64s and CDCs and VAXs up to the current day. The "message forum" mode of commuication is one that has served me well for decades, and I like it. Facebook is just not my cup of tea.
Maybe I'm just a dinosaur and maybe I'm in the distinct minority in not embracing the Facebook/Metaverse world. After all, you said in the previous-but-now-deleted thread that you had thousands of users on Facebook. I've never really seen more than a few dozen active users here on this forum, and would guess that means there might only be a few hundred more lurkers. If that's true, then it sounds like you'll serve a larger fraction of your user base over on FB.
So it may make good business sense for you to move there. But clearly you're going to lose some of the folks who've been active in this forum for many years. C'est la vie.
