In MyProfile, you will see the forum in the top menu. When you click on that menu, two different forums will be displayed, which are general forum and institutional forum. 

The forum in MyProfile is just like other forums in the internet, where you can read, share and comment your opinions related to the forum content. General forum is handled by institutional admins. Hence, they usually share about the institutions and career related posts. Make sure you adhere to all the rules and respect others members in the forum.
