All you have to do is to sign your name below (~~~~) and add a link to your usual talk page; then, when you create or improve pages, add a link to each page under your name, with the score you claim. You can add you user name before, during or even the day after the Challenge (as long as your edits are on the 29th, your time).
This is the scoring system:
8 points - Expand an article with at least 300 words of text, with internal and external links and a picture from Europeana.
8 points - Create a new article with at least 300 words of text, with internal and external links and a picture from Europeana.
3 points - Expand an article with at least 100 words of text, with internal and external links and a picture from Europeana.
3 points - Create a new article with at least 100 words of text, with internal and external links and a picture from Europeana.
1 point - Adding a Europeana picture to an article without expanding it otherwise (each different language version that you add the picture to counts).
Follow the format of the Example below. Remember to put a colon : before the language prefix. Use show preview to make sure your links work; then save page
