You can talk to others through private conversations. To get to them, click on your name at the top right of the screen. Then on the right side of the drop down menu, you will see conversations. Click on that. You will need to know the name of the person you would like to have the conversation with to enter. After that it is just like a regular message.
I saw where you left a message for Tracy regarding people having some issues with recovery. I was doing fine the first week after surgery, but after adding soft foods to my diet, I started having issues with nausea. I was unable to get even close to my protein requirements. Today was my first day to get there and my surgery was 12/6. I have been unable to exercise, so now my strength is very low. I have to get to walking, but even walking around Costco wore me out last weekend. I hope your issues go away quickly.
