Messages should be posted as replies to existing threads so that they form one long "conversation". If you want to start a new conversation / topic that can't be accommodated in the existing sections create your own topic in the last section of the board "Create your own topics here". This is the only place members should start new topics.
If the topic is something that has a genuine lifespan, it will be move to an appropriate section.
Any queries, after making 5 posts you can use the Private message feature to send me a message.
