basically it works like this: you pay for indexing at any of Fast's partners, which at this time is Lycos Europe and TerraLycos (Lycos.com). That gets you into Fast's index.
This index feeds Fast's partners.
The way those partners use and display this index is up to them.
So you should check for preferences of local sites at the partners you are interested in, in your case Lycos.co.uk etc.
