A client asked me to add links to their Tumblr and Instagram accounts on their websites. Trouble is I have no idea how to find them and no idea what their URLs are (or even, in Instagram's case, if it's possible).
There are no search boxes on either site. Googling the issue I am told to go to
tumblr.com/search but this appears as a blank page for me.
Does anyone know how to find users profiles on these sites?
