What code is it to put on a page to allow a visitor to make it their home page please ?
Any help appreciated.
There isn’t such a code except for Internet Explorer and any sensible IE user would have that disabled since not disabling it means that the first dodgy site they visit will change their home page and then lock it to make it harder for them to change it back.
Anyway everyone has an option in their browser itself to set the home page if they want to change it (except if they are using IE and have it locked to prevent it getting hijacked by web pages).
