Create A Forum - Support Forums

Hello,
I believe I still have an old forum I have on here associated with the address I used to sign up to the support forum.
It was originally a .createaforum.com domain based forum, but some time after I added a custom domain to it but it is no longer active.
I would like to get access to the original forum please, either by getting the correct DNS RECORDS to add back to the domain, or for an Admin to change it back to the original .createaforum.com Domain.
Thanks.

Do you know either the custom domain or original create a forum subdomain?

I believe the custom domain may have been
forum.radio-info.uk.to
not sure but the original domain may have been
radio-info.createaforum.com
