If you have a flash question not covered in this guide, or need clarification, please post in PentaxForums.com's accessories forum, or on the Photography site @ StackExchange — I'll try to respond there, and if I'm busy someone else will probably provide help before I can. (And it may well be better help — while I've put a lot of effort into gathering information for this site and organizing it into a helpful presentation, there are plenty of people with more flash expertise than I have. And I have a day job.)
Privacy note: I really detest spam. I'm an individual person, not a company, and while I'll probably save your message with the rest of my e-mail, I'm not going to do anything other than that with your information (unless of course you ask me to do something).
This form is good for quick comments. If you have a longer message to send or want to discuss something, e-mail is better.
