Rory, first off welcome to Rootschat, and what a great start, arriving with really interesting information plus an offer of help.
About your concern that nobody will see it - this is just to let you know that the system most of us have set sends us an alert when a new reply to one of our posts is made, and there's always the 'new replies to your posts' section at the top of pages, so there is a very good chance that Tunbridge and all the rest will know you posted. To make sure I'll send Tunbridge a PM (personal message) which you won't be able to do until you've made 3 posts - if you reply to this that'll make 2.
I hope you enjoy Rootschat as much as I have and that we, in our turn, can be of assistance to you at some point
