We are open to all kinds of suggestions, bug reports, and questions. Please contact us using the web-form. We will consider your letter and reply as quickly as we can. Maximum waiting time for registered customers is 24 hours, even on weekends and holidays, but normally we respond within a few hours. Maximum waiting time for other customers may be 48 hours (usually much shorter). Your questions are carefully read by our support team and, if needed, discussed with our programming staff to provide you with a detailed and competent answer.
