Chez Thierry has done an amazing job of creating an internationalized version of Connections Reloaded 1.5.
He has generated the required .mo and .po files which you can use to translate, using poEdit.
He has currently translated it to French and you can find the same here.
Good job Thierry!
I have a few more modifications in mind for 1.6, and I will officially release an internationalized version of Connections Reloaded 🙂
