Just search on the vBulletin.com forums for the border around the main table. But instead of table borders, use image borders, and then in the head include template in between the "<style>" and "</style>" put this:
Code:
#tabledata {
border: #000000;
border-style: solid;
border-left-width: 1px;
border-right-width: 1px;
border-top-width: 0px;
border-bottom-width: 0px;
}
Then in the styles, in the little text box where it says, "<body bgcolor="COLOR" etc.>"
Set the top margin and bottom margin to 0.
And then...um..do what it says in that vBulletin tutorial to add images.
I am not sure if this would work but I just thought of it.
