As far as I know, GGA still publishes Gekko twice a year. At least they were last year.
I bought the last issue (Vol. 4, No. 2) not so long ago.
I don't know, if they published anything this year yet (Vol. 5, No.1)?
Dactylus from IGS (International Gecko Society) on the other hand, died with Vol. 3, No. 3, dated August 1998.
Actually looking through the last issue right now, there's a bunch of Aussie gecko articles in there, also a nice photo of Carphodactylus laevis and there's a photo of me with Robin Russell (IGS president) and two Aussie herepetologists, from my 1998 trip to Queensland.

It was a great trip.
Gekkota? Let me check that out.
I've got the first issue only. It seems all the summaries are in English, everything else is in German.
I hope this helps.
