I seem to be a bit late on the Pinterest band wagon but I got myself an account and have started playing around. I don't really understand it all yet but I'm certainly having fun!
I'm trying verify my blog at the moment and it says to upload a file that I downloaded to my web server. Sadly, I don't know how to do that and don't really know who to ask. Sigh.
I've also been told to add <meta name="p:domain_verify" content="1b5edb64afafeb8cbca712d7101e9a11" />
