So there's three Calls For Papers right now which need/want more PostgreSQL speakers: Postgres Open, PostgreSQL Europe, and LinuxConf AU.
Postgres Open's deadline is June 26th, so please submit something soon. We're looking for case studies, new innovations, howtos and other talks. Postgres Open is for PostgreSQL's business and user community, so commercial forks and products are welcome. You can also sponsor!
PostgreSQL Europe will be in Prague this year. This will mean higher-than-usual attendance; I'm submitting a talk for the first time in 3 years. You should, too!
LinuxConf Australia wants more PostgreSQL talks! Please submit one. If we can get enough PostgreSQL people there -- especially PostgreSQL people from Australia -- we could hold a miniconf. (As a warning, though, travel sponsorships are limited).
