Hello FrostyGardener. You can opt to receive the weekly email newsletter by clicking your name in the top right-hand corner of the screen. Then click 'My settings' from the list. When this page loads, scroll down to 'Email newsletters', then click 'click to open'. This will present you with a sequence of options - just tick the first box, 'Weekly email newsletter'.
If you have any problems, just let me know.
Many thanks,
