On your Settings page, you'll see your current profile photo with a box under it that says Upload a New Image. When you click on that, your directory on your computer will open.
Find an image that you like in your directory, click on it and then click on Choose.
This will take you back to your settings, with your new photo/image uploaded. Be sure to click on Save Changes at the bottom of your Settings page.
All discussions are located on one page. To get to those, go to Discussions, under the Connect Menu tab. This page includes a list of categories for discussions. Choose one that interests you.
Under each category, you can choose to join a conversation by clicking on it. Or you can start a new discussion by clicking on the + sign.
Discussions are great place to ask a question or to share your thoughts if you want other people to respond to you.
