I'm trying to post an additional comment on to an existing discussion but the Reply button is inactive - duh !!!!!
That might mean that the thread is locked either becauses the moderators do not want the discussion to continue or after a period of time this happens automatically.
Can you give the name of the thread or better still the URL for the message?
If you locate the wording Message 1 of 1 (1 View) on the message that first number is a link and so right mouse click on it and select Copy Shortcut and then paste it into a message here,
