Hello, I would like to make some changes to my advanced guestbook but it won't let me until I set the correct permissions. I've looked on several other forums to get the answer but all I see is conflicting information about what numbers to set and in what location to set them. The changes I want to make are simple I think. I just want to add a link back to my page from the guestbook and stuff like that. Can someone here please help with the permission settings? Thanks.
