In the rankings itself not, thats not how it is intended. Our premium membership is no "pay and get top spots".
But, you could make use of the sidebar where it lists the premium members. Also has an admin setting to control how many shows up.
So you could take the template tag from wrapper
{$premium_list}
and paste it before {$content} to have it appear before rank one.
This however would be sitewide, since its a global tag, to get around it and only have it on rankings page 1, you would do this
Code:
{isfront}
{$premium_list}
{/isfront}
Now you would also want to edit the html file which controls how the look of that premium list is. That is the file premium_list.html and premium_list_row.html
From premium_list.html you would most likely want to remove the heading.
premium_list_row.html you would want to use the same html as found in table_top_row_premium.html
Only possible drawback to this might be that a premium member might repeat. Meaning he might be in the premium list of {$premium_list} and lets say rank 3 or so
