But as you are on the .webeden sub domain it cannot sorry.
If you did have your own domain name then you would be able to point the domain e.g www.mpeoplefanclub.co.uk to your WebEden site and your sub domain e.g forum.mpeoplefanclub.co.uk to your forum.
You would have to host the forum elsewhere but it can be done.
There is a basic forum option, in your software package. If you look at the various pages available (blank, comments, guest book etc) you will see that there is a forum option.
It's quite basic, but good enough to get you started. Thereafter, if you wanted a proper forum, there are loads out there - v bulletin is good, but you need to pay for it. I'd go with the free sitemaker option first and then upgrade if you found that your site warranted a big Full On forum.
You can restrict access to different bits of your forum through the membership tools.
