How to contact me?

Email (Best and HIGHLY Preferred Method):

Email Address: i…

  • I review email on a regular basis. But remember, email is NOT an active form of communication. Don’t expect responses in a few minutes.  Usually, expect a response within 24 hours to a few days.
  • Short emails (in text) are likely to get a quicker response. Attachments are less likely to be opened, sorry.
  • I read all email, though thanks to SPAM, some (well many) are missed. If response needed to something and not received, please resend.
