Hi,
I heard the bad news that ICKI is unsupported from now on. Really disappointing after they promised to release it in Joomla 1.7 too. I had contact about it with a moderator and I understand it was not his decision, but it's poor communication of the developers.
Because of the delay I was already started updating ICKI to 1.7 by myself. You can see at http://joomla17.boerenmacht.nl how far I am. The moderator which I have contact with, helps me further when I'm stuck with something, so that's nice.
I hope I'm able to finish the 1.7 version this year. If someone is interested in the updated files when I'm done, contact me and I'll send it to you!
Greetz.
