This is just a forum, if nothing comes your mind, you can just continue to learn from other discussions and see what others are posting and you too can contribute. Topic should not be an issue, you do not necessarily have to create a topic, let it happen naturally if need be to create one.
I have been doing a lot of reading on this forum, more reading than I contribute to other people's learning. Maybe the person who started this topic is starting to feel the same way like I do feel which is always taking and never contributing, Or even starting a quality discussion. I want to be more of an active user, someone who other people in this forum can benefit from, not just me benefiting from other people here.
