Blair,
I'm not sure if this has anything to do with the new skin but it looks like the users are using the "quote" button when replying to our fixes. Did they have the "quote" option before?
"Reply" is next to the quote button…."Add Reply" is underneath.
Most new members are not looking at that button, so they click 'reply'. I don't think much can be done about that, except to ask the member to click on ADDREPLY when replying to a topic.
