Public strings not translated in chat

Hi,
as discussed in the last thread of mine, translation in general works now (2.0.2).

But I'm working with older volunteers and I need to translate especially the public sections.

It seems that they're part of the po files, but translating them has no effect.

It are stings like "type your nessage here, sound in, etc.). See it here: http://unser-quartier.de/mitte

Best wishes

Daniel
