deprecated, I could add some ideas to the many suggestions monks have offered you. However, I wonder if you have a bunch of mugs^H^H^H^Hfriends outside the workplace, to whom you can present any slides or course examples for comment before your colleagues see them.

In my experience, a local Perl mongers group, if it has technical meetings, provides the ideal forum. Even if you don't give a talk, you can always scavenge for ideas while you chew the collective cud over a pint of beer.
Also, you are quite likely to find advanced Perl programmers at a mongers gathering.
