I love that I can add a thread and see answers to those threads. I like having mean different topics that I can create. I love that using this software, when you movie around in the platform you can see a lot of different topics, such as entertainment or you can search forums using keywords or by topics and be able to save the favorite forums. My favorite is I love that you can get emails to when a topic is added or when someone joins or answers a question. The games forums are really fun.
