@Andy Millne - I haven't thoroughly looked at this yet but thought it worth letting you know just in case it's the bedlington.co.uk platform that's causing the problem and possibly stopping potential users viewing and joining this site.
I decided it's time I added to my collection of hardware bought a new Desktop PC, even though my 12 year old Desktop PC, running Windows Vista & Google Chrome, is still performing adequately .
This comment is via my old PC.
I spent this afternoon going through my list of - shortcuts & favorites = 50, on the old PC and creating them on the new PC - Windows 10 using Google Chrome to connect to the different sites.
49 of them worked without a problem and the one that failed was my attempted connection to this group - Your Internet Access is Blocked.
My first look at - Network - BT Hub - etc etc hasn't given me anything within my system to suggest it's my outward connection that's causing the problem.
Currently on the new PC, as it comes with a months free trial, is Norton Antivirus software.
I expect to resolve this problem next week and I will let you know the cause - or if the problem just went away without me knowing what I had done.
