General feedback
Do you have a question, request, or idea you’d like to share? While I’m not a financial adviser and can’t tell you how to invest your money, I’m always happy to discuss portfolio theory and I love to hear how people use the site. Please use the form below and I’ll get back to you as soon as I can. And don’t worry — your contact info is completely private.
Product questions
For any questions regarding product orders or shipping, please contact customer service. They’ll take care of you far more quickly than I can! But if you have a question about spreadsheet functionality or any of the online tools, I’m your guy. Feel free to ask using the above form.
Not getting a reply?
It sometimes takes several days to catch up, but I do reply to every message. If you ever feel like your question fell through the cracks, be sure to check your junk mail folder.
