Please put an anchor at the bottom of the page that takes you back to the main sub forum. If you are browsing a thread in the gas engine forum and get to the bottom, it would be nice to click a button like before that would take you back to the gas engine forum. This way it also refreshes the page for changes. Using the main browser back button does not do this.
It isn't user friendly to have to scroll back up to the forum address to click the root directory.

Thanks.
