Blocked from certain pages....why?

Hi there,

I put a search in using the seach bar that allows you to search the forums, it gave me the requisite choice of pages, I chose one, clicked through to the page, here I was given the choice of a couple of links, which when I clicked I was informed that I do not have permissions to go to these pages, as these were tutorials posted by a member and I am a member and have been for some years now, how do I go about getting acces to these type of pages?

Cheers
