Dear All,
Let me introduce to you WikIdioms(http://www.wikidioms.com/) - a crowd-source project of multilingual translation of idioms, phrasal verbs, expressions and other kinds of collocations.
The site contains now circa two thousand expressions in several languages(Turkish one of them) and is rapidly growing due to the efforts of our fellow translators.

The project is very young and we really need to better moderate the content to avoid the inaccuracies..Since we currently rely only on the efforts of the volunteers, it would be glad if you as native Turkish speaker could contribute to the project..

Regards, Anna
