There are public BBoards (anyone can read/post; e.g., DBoard) and
protected BBoards (you can read/post/delete only if you are logged in; e.g., Jobs/Resumes).
In the case of protected BBoards, the author of an article can subsequently delete the article which he/she posted.
Also, please note that these are unmoderated message boards. We depend on you to exercise restraint and use proper judgement when posting to these boards.
