I have a link to my website in the footer of my Wordpress template. If someone buys it, are they allowed to remove this link? Thanks!
yes they can remove it
Yup, as _freshface said, the theme is theirs once they purchase it and they may remove any links or credits if they wish
Yep – I usually just make any attribution in the footer a field in the Custom Admin panel – this way users can swap out anything that I have with their own company/individual name and copyright info
