Need a word that describes a biweekly publication
Solution 1:
Periodical has the two senses you are looking for; but why not call it the Personnel Clarion or the Coding Bugle? The newsletter in one of my jobs, most of which informed us of things management should have told us but forgot, was called The Caret.
Solution 2:
I would think a form of "opportunist" would work well. It connotates the idea that it is published at exactly the right times and possibly contains information that would prove valuable to those searching for opportunity.
