Excellent Gareth! I'm very happy to have your help. This will be very exciting to support Firebird, and help with documentation is always most welcome.
Since you are working on Ubuntu and using the 1.x branch you have a nice fixed target for the initial implementation. Keep in mind that later, probably around Q1 2007 when mono fully supports 2.0 .NET there will be additional methods to get caught up due to all the new things the 2.x version of mojoPortal.
I am very much looking forward to that day when we get back to one version of mojoPortal that works on windows or linux
