Cannot attach files to forum posts

Hi there,
I am having a problem with the forum itself. When I create a new post the tab to the left of the options tab does not appear for me and so I cannot attach files like screenshots. I would attach a screenshot to show the missing tab but of course I can't do that ;o).
If there is an email address for tech support I could email a screenshot to show you what I mean.
Any ideas why this does not appear for me?
Do I need to have a different registration to unlock this feature?
Many thanks,
Rob
