Support for zSQLgate is available on a several levels:
I can offer a certain amount of informal support on <mike@sql.z3950.org> to help you get zSQLgate up and running.
You can join the zSQLgate mailing list at www.indexdata.dk/mailman/listinfo/zsqlgate and discuss in that forum any problems you may encounter. I read this list, so I will see your messages; but you may get better help from others who have run into similar difficulties.
For those who require it, it's possible to buy commercial support with well-defined support levels and response times. Send email to <mike@sql.z3950.org> for details.
Feedback to <mike@sql.z3950.org> is welcome!
