That support will be a long, long slog of answering the same set of questions asked largely by people who are both less than expert at using computers and perhaps not their at their most eloquent or polite when urgently trying to complete a task.
The best advice I've read for this is to treat support emails as bug submissions. Questions about your company mean you don't have sufficient documentation, help, user interface, etc etc, and work should be put into shoring up those areas.
Obviously this idea doesn't eliminate all support requests, but I imagine it would reduce the deluge over time.
This could actually be an interesting machine learning problem. Train a system to classify incoming customer emails, and automatically respond with the email template that matches the class of question, and watch your support team get more and more free time.
You mean you have hundreds of people asking where Mankrik's wife is?
More seriously - what do you mean?
