Hello Jon,
We can definitively take you step-by-step to help you start your forum. You can either get your domain name transferred under our registration and continue to use the same domain name or you can choose a new domain name and start a completely new forum.
Please feel free to ask once you signup and we will guide you to ensure that your forum is relaunched successfully.
You may also refer some tutorials from
http://www.eukhost.com/support/ as we have some high quality flash tutorials available in our support section and some FAQ's in our knowledgebase.
Make sure that you signup for the cpanel - Linux hosting plan only and not for Windows.
