Requesting a free site to build a dictionary of Inuktitut

I am the leader of the IUTools open source project:

One thing that would help this project greatly would be to have a bilingual English-Inuktitut dictionary and we think the best way to do it is to engage the community of Inuktitut speakers in creating it through a collaborative wiki site.

Since IUTools is written in Java I thought it would be appropriate to use XWiki for that purpose.

Thx for taking this into consideration.
