You can't submit a URL as far as I know, but as they produce as much traffic as Find UK or Searchy UK - the other 2 meta-search engines other than Ask jeeves, I wouldn't really see them as a big, big player (like they might be in the US).

They are a bigger player in the US than the UK. Their default search used to be split up into results by search engine, e.g. Overture results, Dogpile picks (AdWords), etc. Now the default is to view search results 'by relevance'. It's a good meta search engine IMO.
