Hi Joe,
I've fixed your user profile so that it now includes your new email address, rather than your old one.
To reply to a PM, first click the Reply button.
Then, you'll see a box of text with the original message that was sent to you.
Hit Enter a couple of times, so that the flashing cursor moves down the page a bit.
Next click the top of the text box, so that the flashing cursor now appears in the top left corner of the text box.
Type your reply.
Scroll down the page & click on the Submit Reply button, which is just below a little box of icons.
Once your message has been sent, you'll be returned to the main Private Messages page.
And that's it
