you can write on both your friend’s and your own board. to write on a board, first, you have to be on the profile of the person that you want to write on the board. when you are there, scroll down your mouse till you see the "board" section and click the "write something" menu that you see on the page. write your message here and then click the save button to save your changes.
basically everyone can see your board. there are not any privacy settings for that. however, you can totally remove your board, if you do not want to have it! to do that, go to your “settings” first and select your “privacy settings”. when you are in your privacy settings, you will see a section called “profile information”. you can remove your board by unchecking the box next to “eupee board” option.
if you want to see the all posts of your board, click the "view my profile" link first. when you are viewing your profile, scroll down until you see your wall and click the "see all" link next to it.
if you need any additional information after having checked the questions above, feel free to contact the eupee team by clicking here.
