!!Creating a link

To create a link you have to know the URL you want to link to. Suppose you want to link to http://www.acadeuro.org (the main page of the HQ of Academia Europaea), then you type: Opening square bracket, any name you want to give to the link [[if you want to name the link "Headquarters" it would be "Headquarters"], then a vertical stroke, then the URL, in our case http://www.acadeuro.org, and then a closing bracket:
\\ \\
!Result:  [Headquarters|http://www.acadeuro.org]
