To start a new thread, first select the forum that best suits your thread topic.
In this example, a new member might choose the forum "Roll Call" so they can introduce themselves.
Click on the word, "Roll Call"
On the page that opens up you will notice a dark red button at top right that says, "Post New Thread"
Click on the button.
Ta-da! You are now ready to enter a thread title, the content of your new post, and make sure the preferences are set to your liking.
When you are done, click on Preview and if it looks good, click on "Create Thread" so everyone can see it.
