yes google help forum are there , you can look at related threads and if u do not get any help in forum then you can contact google for answer. But google do not have good number of employees i think. We hardly get any reply .
Just found this. http://mail.google.com/support/bin/request.py You can directly post your problem here, not sure if it's like a ticketing system or the sort.
Try to communicate with help and support center of Gmail, as far as i know there no way to direct communicate with any personnel of Gmail.
You can't contact Gmail directly. There is a link called Help. Mail the guys there if you have any issues with your email account.
