ps I don't know how to add links yet if someone could teach me would be much appreciated
If it's an agency website or something like Vivastreet just copy the url from the top of the page you want to link to and paste it in your post, if it's Adultwork then the link to copy's at the bottom of the page, just below the '(more options)' box.
Don't copy the url on AW, they're massive.
