How do I change my settings?
All your settings (if you are registered) are stored in the database. To alter them click Edit Profile (shown in the pannel for your personal use). This will allow you to change all your settings.
The times are not correct!
The times are almost certainly correct; however, what you may be seeing are times displayed in a timezone different from the one you are in. If this is the case, you should change your profile setting for the timezone to match your particular area, e.g. London, Paris, New York, Sydney, etc. Please note that changing the timezone, like most settings, can only be done by registered users. So if you are not registered, this is a good time to do so, if you pardon the pun!
When I click the email link for a user it asks me to log in.
Sorry, but only registered users can send email to people via the built-in email form (if the admin has enabled this feature). This is to prevent malicious use of the email system by anonymous users.
