Do I have to add tags to content I want to submit?

Yes, you must add at least one tag to the content you want to
submit. It always helps to offer additional details in order to gain other people’s attention and interest towards your submission. Not only do tags give people a better idea of what the content is about, but they also make it easier for people to discover the content you submit. Tagging is a lot easier and more flexible than fitting your submission into fixed/defined “categories” or “subcategories”.
