Hi Seemore, welcome to the forum!
If you want to reply to someone else's post in an existing thread just click 'post reply' at the bottom of their post. If you want to start your own new conversation you need to go to the category that matches your topic and then click the blue 'new thread' button located at the top and bottom of most pages on the left-hand side. It will open a new page and you can just follow the onscreen directions from there. Regards, Shannon
