Idiki: a wiki of ideas.
Idiki is a wiki of ideas organised in categories.
Everyone can add and expose his idea. The first which proposes an idea can also choose its name, then everyone can improve and extend it.
The Idiki's name is the union of the word "idea" with "wiki" and is also a Basque word, which means "to expose".
