Перевод - Греческий-Английский - σε ειδα σημερα στη μηχανη, περασα απο διπλα σου,...

For some reason, when I manually visit this translation page, it says that an expert has asked for my opinion on this translation while I am the one who translated this. Bug?

do you mean this text?

*An expert has asked for your opinion on this translation, in order to decide whether or not to validate it. Does the target convey the meaning of the source?
[I think the meaning of this translation is right]
[I think this translation is almost right but may be improved]
[I think the meaning of this translation is wrong]
[I don't know]

No, it's the standard page that appears to anyone. But here people who usually translate from Greek into English will have a special poll request appearing with the number of translations they can help to evaluate (it's on top left of the page, entitled "Help evaluating translations")

Ah OK then. Although it's weird to ask the guy that translated to rate his translation. :-) Anyway I'll just ignore it.
