Hi...good job on the pictures....perfect size and pretty room
When you want to START your own thread......Click the Button in the Upper Left corner.....it says NEW THREAD....(like you did here starting this thread)
When you want to reply to someone click the Button that says POST REPLY....left hand corner
it's very easy.
The Blue BAR across the page has 'New Posts....that is so you can see all the posts since you were last on the site.
