He pensado que si no teneis fb, quizás no podais entrar a leer las bases. Os lo dejo copiado aquí:
"The 1st "WORLD PUZZLE DAYS" (WPD)
will take place on sunday, 3rd of march 2013. (2013-03-03)
Everyone all over the world, no matter where you live, is invited to participate. The rules are very easy:
1. Your puzzle has to be a 2000 piece-puzzle. (Not 500 or 1000 or 3000, and so on!!!) The same amount of pieces is what unites us. This page is NOT another page to show all of your puzzles, it is thought for ONE event and ONE puzzle a year.
2. You may choose your own puzzle. First I thought we should master all the same puzzle. But this would be very difficult, better said "impossible". Puzzles you can buy in Austria are not available in Japan, Russia or Argentina... So you can choose YOUR puzzle. Only: we all have to have the same amount of pieces! >> 2000.
3. The puzzle may NOT be started before the beginning on 3rd of march 2013! (As I just said, this page is not for showing puzzles (to do this you have a lot of other pages or groups on facebook), the WPD is to bring us together and make us feel ONE doing the same at the same time. No matter if you are sitting in Shanghai, Berlin or New York. And the goal will NOT be to be the fastest!!! So don't show older photos and be honest!
4. Every night (your local time) you let your puzzle for tomorrow you should upload a photo of your progress to this page.

Every participant receives an own album where he will put his actually stand of progress. On days off without progress of course you don't need to upload a photo of progress.
5. On saturday, 2nd of march 2013 you upload a photo of your pieces -BUT WITHOUT THE BOX PLEASE!!!- That is to show that your puzzle is still unmade. To show NOT the box of the puzzle is to let a surprise for all the other participants who will not know what puzzle you are going to do.

This is more interesting for everyone. By coments the other one can guess what it will be, if they want...
6. To do a puzzle should relax. To do it "together" and share it between the other participants should raise the fun and make us feel ONE. To look who will be the fastest would be a fun-killer!!! Nobody can compare different puzzles. And even if two puzzles are the same it's not recomendable to compare who is faster because by this way you only sow stress!
7. The place of the event and where you upload your photos of progress is HERE on this page. You have to put your photo allways in YOUR OWN album. Try to put it in the right album, please, and not in the one of another participant. And also don't put it on the wall! By a click above on "Foto" you find YOUR album. I would have to replace it in your album and all your comments would get lost because I would have to save it on my pc, cancel your photo and upload it one more time in your album!!! (Remove photos from one album to another is NOT possible!)
8. Everyone can participate. No matter where you live, your age or religion. We all are ONE and everyone is welcome and invited to participate.
9. It is not duty but it would be better for all of us if we write here only in english. My english neither is good but if somebody writes in hungarian or german he/she excludes the other one. Better a poor english (as like as mine) than a confusion of a lot of tongues.
(If you would like to participate, but you are not able to write in english of course you can also participate. Most of the event is only being together by showing your photos. It's not necessary to write comments. And to try to do that in english you can use for example
http://translate.google.de/ )
10. Nice would be also if we all could see your nationality in your profile. Perhaps you will have interest looking the puzzles and friends who will participate like you. The same right should have the other one looking at your puzzle.

That's also more interesting. So perhaps you can see that somebody in Oslo is doing the same puzzle and at the same time as you do in Barcelona or Rome and you can compare the different ways of mastering it.
I hope deeply you will appear and participate in large numbers.
You still have two mounths for looking and buying a beautiful 2000 piece-puzzle according to your own taste. There's only one limit: No sexual themes! In this case I have to cancel your album. The WPD are for every age, kids including. As you have bought one puzzle you can write here that you will participate. (But let your puzzle closed until 2013-03-02!)

So we all can see who will play together with us and from which countries.
