We've just identified (and resolved) an issue with some outgoing mail from our helpdesk. It appears to have started on April 9th, so if you opened a helpdesk ticket and seemed as if we didn't respond, well, we did, but the helpdesk's outgoing mail queue was not letting all the messages through. We're retroactively sending out as many responses as we can now, but if you have an issue that you reported between April 9th and now and haven't received a response, you may want to open up a new ticket so we can be sure to get a response out to you as soon as possible. We're really sorry about any problems this may have caused.
