ROS Discourse is for news and general interest discussions. ROS Answers provides a forum which can be filtered by tags to make sure the relevant people can find and/or answer the question, and not overload everyone with hundreds of posts.
If you’d like you can reply with a link to your answers.ros.org question, but in the future please start there.
Also related please don’t double post questions it’s considered bad etiquette. And if you provide more details in your question it will be easier for people to help you get to where you want to go. The support guidelines have suggestions for how to ask good questions.
