I couldn't figure it out either (No tabs ) until I clicked on "Community" at the top ...then the tabs are there in the middle top ..over names & pics. Hope this helps.
Just to reinforce what the others said. Look at the top of the page while on the cummunity page.(Not the very top!) You will see three tabs like file folders. One is Public, one is Personal, and one is Private. What we are now in if the Public tab.
What Camylow said, Damaris. Also, if the Private tab has a +1 or +some number after it, it means you have Private Messages, just click on the tab to go to those messages. Good Luck!! Marji
