Hi Paul,
I can answer your first question for sure. Yes, we would be releasing JobBoard version soon after J 1.6 stable version is announced. Needless to worry about the same. However, to decide between which one to settle down for now, would be very difficult to say, as J 1.6 will still take 5-6 months to settle down and for other extensions and templates to be made available. However, we would be providing with the steps to upgrade to J 1.6 for our components, so future upgrades should not be a problem.
For the second question, i shall ask the JobBoard dev to reply.
Regards
Arvind
