Ok...in English would be cool...
Consider the age thing...
Ok, I'll try, lol..You search for the forums you are a part of and can set the app to remember them and your log in info. You can go back and forth between your forums and can navigate through them pretty easily. When you set up subscriptions to threads, it gives you an instant notification each time there is activity in that thread. Take this thread for example..I subscribe to the thread and every time somebody posts in here, it sends a notification to my phone app. I click on it and it brings me to the post. It also has most features that are available when you view these threads like you would on the computer. You can set it up and customize all of your options and it is much easier to use then the mobile site or their phone app. Do you use an android phone or iPhone?
