Still a lot left to do but I probably will not be able to get back to it much until next weekend.
I do now have the domain redirecting to this site from the default page, so people should be able to freely access the site for viewing from this point on.
I am not completely sure if I have addressed the issues with email.
If it works then people should be able to register for the site.
If not I may have to look into other ways to allow people to register until I am able to correct the issue.
