Been here a long time (registered in Jan 2017) and for unknown reasons the forum went down a couple of years ago and my last post on here was in Sep 2021. 
It's only this week that I have found the forum is finally working again. I almost gave up bothering to check occasionally.

Anyway, seems very quiet in here. Hopefully it'll pick up sometime soon once other members realise it's up and running again.
