At the moment, DBForums doesn't have anything specific for CA-VO. Once upon a very long ago, I was the sysop for the CA-VO forum on Compuserve so I can answer more than a few questions about it. We occasionally get questions about Clipper and CA-VO, usually in the Other PC Databases forum.
If there are enough interested users, I'd be willing to create a forum specific to CA-VO, but so far we haven't had any more than an occasional question.
In theory, theory and practice are identical. In practice, theory and practice are unrelated.
