Do you write PL/SQL? Me too!
Trouble is, sometimes it's hard to decide how to structure your packages - particularly in an APEX project. Over at the PL/SQL Challenge website run by Steven Feuerstein and friends there is a page dedicated to roundtable discussions.
I submitted my question not so long ago and hope to get some interesting responses. Why don't you give the site a visit and contribute? The discussions usually last for about a month.
Past discussions are available to view - last time Steven asked for use cases for DBMS_RANDOM. You could even test out your PL/SQL while you're there and take a few quizzes.
