We welcome the exchange on our channel and look forward to receiving questions, suggestions and open discussions. We appreciate a respectful interaction with each other. In this context we would like to point out our community rules: https://www.ista.com/corporate/company/community-rules At ista, we value diversity and inclusion. That is why we place great emphasis on gender-sensitive language in our communication, which we use to address and portray all genders respectfully. To this end, we use the colon. Where we do not refer to specific individuals but to groups or bodies, we continue to use the masculine form in some cases. This applies in particular to technical or contractual terms, which by definition include members of all genders.
