This is how to make a new topic for discussion
FYI: a "topic" can also be called a "thread"
So you want to make a topic about, let say, your dog Fido.
When your on the forum index find the section that best fits that, in this case it would be the pets section so click that.
Then inside there click "New Thread" button, looks like this it is on the top left of the list of threads in that section, look below....
The hard part is done.
Now just give it a title.
if you want to you can add a few key words to the tags box
type in your message
hit the "submit new thread" button
