Unfortunately photoshelter does not provide nameservers. Photoshelter support told me I had to 'park' the domain with the current host (which is WP's automattic) and then I would have access to DNS settings to set up a CNAME.
I've parked the domain, and I've tried to create a CNAME DNS record under the 'edit DNS' link next to my domain name in my wordpress profile (I don't have access to DNS manager under automattic) and created the DNS record 'CNAME tysnaden.com tysnaden.photoshelter.com.' But I don't think I've done this correctly.
What would the proper DNS record be to do this?
