Welcome to Wikipedia and thank you for your contributions. I am glad to see that you are discussing a topic. However, as a general rule, talk pages are for discussion related to improving the article, not general discussion about the topic or unrelated topics. If you have specific questions about certain topics, consider visiting our reference desk and asking them there instead of on article talk pages. Thank you.
