next time I'm over glasgow way buy me a pint and I'll give you the answer.
seriously, I've never seen it. TGPs of course but LLs no. It would be interesting to see done, sites like
http://www.sexy-search.com/panties/
for example have their links as Featured sites then a link under it that says
SHOW THE STANDARD SITE LISTINGS >>
taking you to
http://www.sexy-search.com/panties/standard.html
would work well for paid listings.
