Post in the right forum - The forum index is broken down by categories. There are specific forums for applications, devices, device hacks, carriers, general chat, etc. Unique forums exist for a reason. Before you create a new thread, please ensure it is being posted in the most applicable forum. Threads discussing an Android application are generally not device specific, and should be posted in the Apps forum.
