There are times when PC is actively updating things , most of the time it happens 2-4am’ish I have noticed over the years.

But there are times PC like any other site on the Internet will have a glitch or hiccup and needs sorted out. It’s a free site so I’m doubting DocJohn has a paid service 24/7 to maintain it altho I could be wrong. The site alone I’m sure is quite expensive.

As for posting links? Or rather not being able to ??! I have no clue , I use Tapatalk and I don’t think it’s an option anyway.
