Probably due to idiots and trolls, which is inevitable with any Facebook group sadly. Shame as it was (is?) one of the very best communities, and I wouldn't consider owning a VX220 unless I could access it.
Got it thank you, and safely in. Immediately reminded me of how good communities used to be, before corporates took over social media. I can totally appreciate why it makes sense for the group be invite-only these days.
