Wiki

From DPBwiki

Officially, by WikiPedia:

A Wiki or wiki (pronounced "wicky", "weekee", or "veekee") is a website (or other hypertext document collection) allowing users to add content, as on an Internet forum, but also allows anyone to edit the content.

Basically, it's a bunch of editable pages. You can add info. Someone else can add info. You can edit each other's added info. The finished collaborative effort is called a wiki.

So that's that.

Of course, in the great land of DPB, this technology will doubtless be put to good use. Or at least used for poo.
