For those not familiar with Wikipedia it is a collaborative
encyclopædia where anyone can edit any article. If, for example,
you notice something amiss in the article on Hrafnkels saga you
can click 'Edit this page' and fix it. (If you were so inclined
you could also do something silly to the page but past versions
of pages are stored so vandalism is easily, and usually quickly,
Most of the Icelandic sagas don't even have an article yet so
there's plenty of scope for knowledgeable contributors.
