(from wikipedia)
A wiki is a group of Web pages that allows users to add content, as on an Internet forum, but also permits others (often completely unrestricted) to edit the content.
In this case ANYONE can "edit" a page. In case that spammers would be paying us visits very often, we would have to restrict the editing access.

Because we are fed up with intelectual properties and restricted access to knowledge.
Becacuse we believe in collaborative learning instead of the classical competition-based educational system.

It's REALLY easy. You don't need to know anything about HTML or web editing.
Just press the "Edit Page" button and you will see a box, and to your right there are the syntax conventions.
Although it's easier to look and copy the "code" from the editing box of some other page which structure you want to follow.

Just experiment!
Don't be afraid to change something, you can always press the "history" button and revert to a previous version of the page.
If you want to create a new page, just write it between [ [ and ] ] (without spaces!). if you save your changes you will see a red link,
it means that the internal link points to some page that doesn't yet exist. If you click on it you will be able to start a new one.
Don't forget to point to the [ [ start ] ] page at the end so it is easier to go back to the main page.
Happy editing!
