I note many comments over the time I've been here from people complaining the 'contact us' form isn't working or being responded to.
Well I've had responses to several queries, all by email.
So it's working for me.
Might be that people need to check the (presumably) fake email addresses they signed up with and perhaps they may find responses from the site staff there?
On the other hand, maybe there has been an enhancement in customer service recently since I've only started using that form in recent months.
