Actually, you don't have to make a topic for the members, besides there are so many topics here, I'm afraid if you force it there will be many of the same topics. It's better if you develop your knowledge later there will be topic ideas that are worthy of being discussed in this forum.
A lot of knowledge is really needed nowadays, especially with the existence of a lot of social media where all kinds of positive and negative information. We must seek deeper information. By knowing more clearly, we can determine our attitude towards the information we receive so that there will be lots of ideas for discussion purposes.
