If you opted to post a copy to your board, put brackets around any parts that should not be included. For example, username and password. (Note: by default, user information has these brackets to exclude it. If you wish to change that (not recommended), remove them in the preview box below.)
Sample:
{Your username is: "$username"}

It removes text that should not be included into the bulletin post.
