Hi Carol,
Here are some steps to help you respond. I'll start first by getting you to your inbox.
-On the top of each page you are viewing, there is a private messenger icon, click on that.
-Look for where it says inbox status. Either click on the link Go to your Inbox or click on the inbox icon.
-Click on the private message you would like to read. Once opened, on the bottom right side (under the message) there are a bunch of icons. Click on the reply icon.
I hope this helps. Take care.
