What is happening in Sweden?

[Ruud]

Is there anyone who can tell me why this site is suddenly so popular in Sweden?

What have you done, Laura?

TIA

Ruud.

I posted a couple of places that this was the place to find harder
Sudokus than 'Nordstedt's Sudoku Extreme' (a fairly popular
book of hard sudokus here). I have no idea if this has had any
effect, though.

I found out that the links were coming from this site: http://www.derigomedia.com/

It seems to be some kind of e-mail newsletter service. In Swedish, so I cannot read it.

It's not your fault, Laura
