Have a question about something you can't find in a Video or the Help Docs?

The only stupid questions are the ones we are too shy to ask.
  1. Post your question in the JCapper 101 section of the JCapper Message Board.
    I'm an extremely busy guy. Even so I try to read the JCapper Message Board at least once a day. We also happen to have many active and friendly JCapper community members reading the message board too. Many times somebody from the community will answer a question before I even get the chance to read it.


  2. Email your question to me.
    I try to read and answer all JCapper emails at least once a day. If you email a question to me I'll email you back an answer - usually within 24 hours.

Bottom Line: - If you have a question or need help with the program - you only have to ask.
