Jeff,
Check out the SMR forums. (http://forums.smr-forums.com:8080/) They have an official forum for ACI (like this one is for Outlaw) there.
SMR stopped hosting the ACI forum a couple of weeks ago. The owner of ACI, Mike Dzurko, posts quite often in the
speaker section of AVS Forums. Folks can also go directly to ACI's website:
