I think it's mostly quite straightforward, but in the interests of making things as easy as possible, here are a few helpful hints
- If you click on 'Profile' in the second row of the top bar you can change various things to do with your account. If you then choose 'Profile' from the options on the left a list will appear underneath to allow you to change your avatar, signature, and your password and email address
- If your choose 'Board preferences' you can choose to get email notifications for various things, set your time zone and so on.
- You can also access your PMs through your profile, or by clicking on the link on the second row of the top bar, which also tells you if you have any new messages.
