If i make a forum right now under my subdomain www.mydomain.lunarpages.net/forums and later once my registrar carries out the domain name change, will my forum change into my domain name www.mydomain.com/forums automatically by itself? or will I have to change it myself? If so, how?

also this is a new lunar account using the domain name that was set to an old lunar account (that is canceled but not yet expired). will my registrar be unable to set the domain name to this new account until the old one expires? I already replaced the new server name info w/ the old. so the old account shouldn't be set to that domain name now anyways right?

also, are there restrictions to this board? like a certain amount of posts, threads, members, etc since many 'free' boards have restrictions like that but this board isn't really 'free' either right since we paid for an account?

please give me a reply asap. thank you.
