The lectures are good, but it seems that Infraon has no conscience for selling learning materials from 2020 when it is now 24 years old.

You said in the lecture that you would provide a form for bulk uploading from catalog ads, but where can I find the relevant files?

Where on earth can I ask questions? You can't upload a lecture as if you can ask questions, and explain the lecture like this. The explanation is too vague, so you have to explain each page link one by one. This lecture is worse than YouTube, really.

Thank you for the great lecture.

I learned a lot, thank you!

Good, it was so good
