Thanks for the reply techsupport.
I did read that page and it covers the basics but what I am asking is, and I hope I can explain it correctly, of the 9 panels in the page, I am happy with locations 1,2, 3, 4, 6, and 8.
Of the remaining panels 5, 7 and 9, is there a list anywhere, of the sites that will come up, if I am not satisfied with what is selected for that panel or do I just keep deleting the suggestions supplied till I find one I am happy with?
Take panel 9 for example, if I delete the suggested fill-in, can I select a site from somewhere, say from a list available for that panel, to pin it in panel 9 or does the system just randomly come up with suggestions from some mysterious algorithm?
