If you have a problem with a user's posts relating to the above rules and guidelines please use the report button rather than having an argument with the particular person on the forum.
Taking a thread off-topic in that way spoils it for the majority of users.
A forum moderator will be able to deal with the reported issue as quickly as possible.
(The report button is at the top-right of every post and looks like this
if you use the default theme.)
