You can reach us via the contact page. It goes to a shared team mailbox, so your message will find its way to the right person - it just might take a little time depending on what's going on.
If you need a faster response, your best bet is the Community. Several admins and moderators check the forums throughout the day, so a post there tends to get picked up much more quickly than an email. It's also a good place to go if your question might be useful to other people - chances are someone else has wondered the same thing.
