Is this the offical Ardor Bitcointalk thread ?
Yes. However, Damelon (the thread starter) is not very active at this moment and has also stated that he currently isn't following it. But there are other Ardor experts like martismartis regularly answering questions.
is there one for Ignis ?
As far as I can tell, no. There would be no point also, as Ignis is not a third-party childchain but a main part of the Ardor ecosystem. The only reason to have a thread about Ignis would be a separate "speculation" thread (e.g. to be able to talk about exchanges and so on) but in my opinion that would even draw activity away from this thread here.
Everybody can, however, obviously start a thread like "Ignis: Moon or doom?" in the
shill-spam altcoin speculation forum
