G'day Rachel from South Dorset and Welcome back to ROG. Beautiful part of the country.
A very nice build may I add and being the POME geek that you are, (Aussie joke not to be taken seriously) I'm sure you will be able to assist us in helping other ROG enthusiasts and I trust you too will enjoy your stay.
BTW, No such thing as a dumb question here.
We owe our existence to the scum of the earth, Cyanobacteria
