You need approval to be accepted. If you are not a member then you will not be accepted as a forum member and you will have limited access to the forum (not all parts of the forum are visible to non-members).
Passwords are so secure the forum administrators do not know what they are so please keep your user name and password safe.
How do you keep your password safe? Either a program to keep multiple passwords safe or just enter them into a text editing program. Make sure you save the file with a suitable name, “Password for BHPFC forum” for instance.
