Please consider these guidelines:

  • We are a small company without a huge support organization, support are currently answered by our lead developers during office hours and we intend to only have developers with full insight into code base as a first point of contact - this is to ensure fastest possible problem solving.

  • Use a descriptive subject, "Need help" is a bad example of E-mail subject. A good subject looks like "Crash when trying to write file to my disk".

  • Supply screenshots and log files when possible, this speeds up the support ticket handling. Find standard log file locations below.

  • We answer support E-mails in the order they come in. If you have an urgent matter that has put your production to a stop - begin subject with the word "URGENT" in capital letters and we will prioritise the matter.

  • We answer support E-mails during office hours (see below), outside these times we answer sporadically with any guarantee on response times.
