After you are familiar with navigating the site, you might find a topic of interest and you can decide to do one of two things: Reply or begin a new thread. We will now cover how to reply
In order to reply to an existing message or "thread", you navigate to this "thread" or message and look for the reply button which is located in the upper right portion of the blue bar that contains the message. The reply button is next to the notify button.
After locating the reply button you should click on it and you will be taken to a new page where you can enter your name so other people can identify who this message is from, just like an email. Below you will find a box where you can type your response including any links to pertinent websites (as with e-mail) and finally if need be you scroll down in your browser window to find the post, preview and reset buttons. As might be obvious, the post button posts the message as is, the preview can allow you to see how the message will be displayed before posting it and the reset will clear any text you have entered.
