There's an old post on this forum where it says that you can point a CNAME of your own domain to your hosted invisionzone.com site and it will work. Instead I get the error "This Community is Temporarily Unavailable!". 

I am trying to point...

http://forum.artbyte.me

To...

http://applebyteme.invisionzone.com

Is this possible and if so is there an online guide for it somewhere?

Have you read?

 

Thanks for that, now found where to add a subdomain.
