The article MH Frequently Asked Questions (FAQ) with Answers appears monthly in the newsgroup ‘comp.mail.mh’. While very little is there that deals with MH-E specifically, there is an incredible wealth of material about MH itself which you will find useful.
You can find FAQs on MH-E by searching for labels:support on the Tickets page on SourceForge. If you don’t find the answer to your question, file a ticket and your question will become a new FAQ!
