selfy

Up up at the very top, click where it says "selfys profile". Should be in the middle of the blue bar way at the top of the page.

Now, look for:

Personal Information: Email, password, signature, biography, IM, etc.

Click the word edit across from it.

Now scroll way down the page until you see
Privacy Preferences:
Do you want to be visible on the "Who's Online" screen?

and select the radio button for yes. Then click submit.

If your really still lost, let me know and I will make some screenshots of what to look for.
