Now you can see in the Board List window the mp3ogg board has been
added. Not so fast! This board is not secured and is
therefore very spammable. If you start updating the board in it's
unsecured state, then expect to receive no useful files, well unless
spam is useful to you. ;-) So the next step is to select
the mp3ogg board and then left-click the icon highlighted in yellow.
That will bring up another small window:
When this window opens, Public board is
selected by default. To secure your selected board, click on the
Secure board button. Then you will be able to type or paste the
Public Key in the appropriate text box to begin retrieving messages and
files. Once you have entered the appropriate Public key for your
selected board, click OK on the window and the board icon will change to
a lock. In the top picture on this page, boards that have already
been securely configured are shown with a lock icon. You are now
ready to update your newly secured board and begin to receive any
associated messages or files for that board.
