The best place to ask any questions concerning OpenGroupware is on the most specifically appropriate mail list; that is where your question is most likely to be seen by those most likely to provide an answer.
The #ogo channel on Freenode. While fairly quiet OpenGroupware developers occasionally hang out here; please follow IRC ettiquite - which means don't pop in, ask a question, and then pop out if you don't get an immediate answer. General questions are better off on one of the mailing lists.
