Why can't I log in?
Have you registered? Seriously, you must register in order to log in. Have you been banned from the board? (A message will be displayed if you have.) If so, you should contact the webmaster or board administrator to find out why. If you have registered and are not banned and you still cannot log in then check and double-check your username and password. Usually this is the problem; if not, contact the board administrator -- they may have incorrect configuration settings for the board.
Why do I need to register at all?
You may not have to -- it is up to the administrator of the board as to whether you need to register in order to post messages. However, registration will give you access to additional features not available to guest users such as definable avatar images, private messaging, emailing to fellow users, usergroup subscription, etc. It only takes a few minutes to register so it is recommended you do so.
Why do I get logged off automatically?
If you do not check the Log me in automatically box when you log in, the board will only keep you logged in for a preset time. This prevents misuse of your account by anyone else. To stay logged in, check the box during login. This is not recommended if you access the board from a shared computer, e.g. library, internet cafe, university cluster, etc.
I registered but cannot log in!
First check that you are entering the correct username and password. If they are okay then one of two things may have happened: if COPPA support is enabled and you clicked the I am under 13 years old link while registering then you will have to follow the instructions you received. If this is not the case then maybe your account need activating. Some boards will require all new registrations be activated, either by yourself or by the administrator before you can log on. When you registered it would have told you whether activation was required. If you were sent an email then follow the instructions; if you did not receive the email then check that your email address is valid. One reason activation is used is to reduce the possibility of rogue users abusing the board anonymously. If you are sure the email address you used is valid then try contacting the board administrator.
