Clicking on "Quick Links" at the to left of the screen gives options to show those posts which you have not SEEN before. Saves trawling through everything every time. "View unread posts" shows you posts that you have SEEN ie.seen that they exist, but have not actually READ.
Not only are there FAQs (Frequently Asked Questions) at the top left of Board Index, which answer many common user problems, but there is also a SEARCH facility at top right.
Have a look at the "User Control Panel". This is seen when you hover on your Username at the top right of the screen - it enables you to personalise your view of the Forum.
Do you know that you can contact other members of the Forum through the Private Message system? Again, have a look at the User Control Panel. This means that you never need to reveal your personal e-mail address.
