allmost there ;)

To be coherent with the rest of the translation, I would remove the "." at the
end of these: (you only put a "." at the end of these two options, other options
don't have the point at the end.)

[PrefDlg.LocalSettings]
ANSILog=Αποθήκευση αρχείων κειμένου με κωδικοποίηση &ANSI/MBCS.
UnicodeLog=Αποθήκευση αρχείων κειμένου με κωδικοποίηση &Unicode.

I don't know Greek, but this seems like an error, or not?
A forgotten accent on the second letter in "Αυτόμ."?
(it is there in "AcceptReqListNoFiles", so maybe an error?)

[PrefDlg.IMGenOptions]
AcceptReqListAll=Αυτόματη αποδοχή κάθε αίτησης
AcceptReqListFiles=Αυτόμ. αποδοχή μόνο μεταφ. αρχείων
AcceptReqListNoFiles=Αύτομ. αποδοχή όλων πλην αρχείων

Some strings which are still too long:


This is too long only if the menu is highlighted; When it is selected and
becomes bold, part of the text is cut off:

[Dialog.Preferences]
ListPersoStat=Προσωποποιημένη Κατάσταση


These doesn't fit in various pulldown menu's like in the status-select menu in
Boss Protection or "auto change status after x minutes" pulldown menu (this is
the shortest menu, so check it with this). Also, if you change these, don't
forget to change them also in other keys (to be coherent).

[MessengerEvents]
AppearOffline=Εμφάνιση εκτός σύνδεσης
Away=Δεν βρίσκομαι στον υπολογιστή


These don't fit at all. Text is cut off:
[Dialog.ContactInfo]
MaybeOnList=Είσαι, ή δεν είσαι στην λίστα αυτής της επαφής (πληροφορία μη διαθέσιμη).
ContactPlus=Η επαφή έχει εγκατεστημένο το Plus! (τελευταίος έλεγχος: %s).


----

Then some other incoherent things:

sometimes you use ",...", sometimes you use ", ..."
(thus with the space inbetween). I suggest to put a space inbetween everywhere.

sometimes you use "text:", sometimes you use "text :"
(thus with the space inbetween). I suggest to remove the space everywhere.

About the not translated words: Isn't there any alternative? Or can you make the
actual sentences shorter, so the words can be translated? It doesn't look very
good when there are still english words left. "Forum / IRC" in the about window
is of course a special case. I mean, no sentence to shorten here, but isn't
there any alternative you can use? I'm just wondering though....
