I am that other User ratfink wrote about.
I asked him for the Source, because I was interested in how it worked (I do the German translation of Acquisition at
http://acquisition.draketo.de, and I got a reg# from him for that).
At the time he sent me the link
http://acquisitionx.org it was already outdated (but only about one month).
At that time I thought him just too lazy to update the code. I pulled it down via download whole website of iCab.
Since 0.966 is a really far step from 0.851, only giving that version of the code is somewhat strange.
I still hope he'll change his attitude, for Acquisition is great, and I don't know if that level would still be kept, should he stop working at it.
