You can always email OPP's friendly, personal Customer Support team for help: firstname.lastname@example.org
Please be as specific as possible when you email Support with questions, and always mention your URL! This is for your benefit, as it facilitates a speedier response to your questions.
A note regarding phone support, and the absence thereof:
As a small business run by artists, we don't run a phone support line. This is an important way that we keep the cost of our sites low for our wonderful artist customers. However, we are very happy to answer any questions that you may have via email, and we try very hard to be prompt and thorough in our responses. Thank you for understanding!
