Hi Joe,
As a temporary solution the redirect facility works very well. I've tried it out and moved it around in the NavBar, so thanks for suggesting it, and showing how to use the redirect facility. In fact, I'll be using it on the main site.
I appreciate that, in theory, the two sites act autonomously from one another, but the public facing part if the site should be the dominant area - after all this gives access to other parts that are subsequently created (e.g. a Members' Area). Logically, the "Home" reference on the NavBar should always take you back home (to your public front page). (And the same applies to the logo.)
I agree that if you were to make the above change that there would need to be a second home link in the NavBar for each of the private sections created (e.g. Members, Committee, Admin etc). This could be initially labelled something like Members Home or Member Zone (but have the facility to be configurable locally by administrators).
Again, thanks for the advice and giving it consideration.
