Currently, I am not publicising it because I want to build up some reading material first.
Well, that explains why Joe Public would have problems accessing your site – which is just the way you want it atm, yes?
they have all had Error 404 messages come back at them
My guess is that this is just because it’s such a long url right now and they are mis-typing it.
is there a way to lose the https://www. part.
Yes. Your hosts may be able to handle this for you. Try asking them. If not, you can add something to your root .htaccess file that will redirect www calls to the bare domain name or vice versa.
To be perfectly honest, I think this is all something that can be left until you are ready to launch the site publically. For a start, you could get rid of the brokenbonds
part by allowing WordPress to take over the root domain relatively easily when you are ready to launch.
