> Is this the forum for AOII and Hi Opt II
> card counting technical questions?

This forum is aimed at computer-related topics. If, for example, you were trying to run a sim on SBA (or similar software) comparing AII and Hi-Opt II, and were having problems, then this would be the place.

However, if the questions just concern the counting systems themselves, then the main page would be the best place for it.
