Horay !!
I am ready to get my hands dirty Ben. Let me know what do you want me to work on (or do you want me to choose an area?) and I'll do it.
I am updating the OpenACS 3.x documentation (just finished the Install Guide). I should have a beta version of the PL/SQL-to-PL/PgSQL-HOWTO later tonight.
I should have some better documentation for PL/PgSQL (that will be contributed to the PG team) later this week.
