NetObjects have now abandoned Koken and the unofficial support forum is currently (permanently?) offline too. That makes the Redit group (https://www.reddit.com/r/koken) and here about the only places to post on the topic - so here goes.
I've just come across a petition that has been started (https://www.change.org/p/netobjects-...-to-opensource) calling on NetObjects to publish the code to Opensource. It's such a great product that it would be unforgivable for it to remain abandoned, so please do consider signing...
FWIW, the person who started the petition has been in contact with Todd Dominey, one of the creators of Koken, and you can see a summary of the conversation here: https://www.change.org/p/netobjects-...rce/u/24998242
