you see now i'm creating a link object named link5, its text is
XMLArsenal and it's address is (the old) sourceforge address.
afterwards in 208 i push the link into the linkarray. so basically you
have to create your own link object, apply both values and push it. if
you want a link out just don't push it into the array.
