These values are gconf values. Being a user, to change them in gconf you MUST
set the english value. It is IMPOSSIBLE for greek users to guess the english
values if you translate the values to Greek only. ;-)

Proposal: Put the greek translation in brakets after the english value.

"ask" (ερώτηση)."

Please also check the other strings.
Might be worth to explain this issue (gconf key values) to the other greek
translators to avoid this happening in the future, don't know...
