Also take a look at www.databasedevelopmentforum.com

There are forums for both Firebird and NexusDB, although the NexusDB
forum is empty. However, Martijn seems to be one of the main persons
behind the site and since Database Workbench started off a a tool for
InterBase and "Database Workbench light" will be distributed with
NexusDB in future versions, I would be surprised if he didn't run to
your assistance with some brilliant answers to whatever
Firebird/NexusDB question you ask at that site.
