Anyone can leave a comment on any post or in the forums.
You will need to complete your name and your email address at least.
Please be polite.
Comments will not be censored in any way unless they are abusive / threatening.
Please remember that your comment will remain on the site for a long time. If you feel very strongly about a topic or a comment someone else has written then it might be wise to take a few minutes to consider your reply. Comments will not be edited or removed (but see below).
There is nothing stopping someone from leaving false details. But bear in mind that comments with a real name attached will be given more weight than from someone who chooses to remain anonymous.
