Here's an example of what you need to enter. You could just copy the following and then paste it into the diaglog box when you go to "update profile."

Note: to have the link appear, after you paste the above, you'll need to remove the space after the opening bracket. Don't make any other changes. If I remove the space here, all you'll see is the link. The opening and closing code [in the square brackets] turns the address into a clickable link.
Good luck! Rhonda
