How do I put my social profiles on my website?

In the editor, under Your social links. Paste the address of a profile — the one your browser shows when you are looking at it — and we work out which service it is and draw the right mark at the foot of every page. That block lists every service we can draw, with directions for finding your own address on each, and you can pick what colour the marks are. Nothing shows up on your website until you publish, the same as everything else in the editor.
