Forum

The Forum must have the following structure: the top level is represented by Topics. A forum can have one or more Topics. Each topic has a name. Below each topic are Threads. Every Topic has one or more Threads. Each Thread has a name and text description of the thread (usually the text description is the description of the problem or the question that user has and that has been the reason for creating the thread). Below Threads are the lowest elements, which are Posts. Each thread can have one or more Posts. Post represents the ideas, suggestions, or something that the user has posted in forum’s thread
