**pdxfunc** is a study/user group exploring the world of functional programming, based in Portland, Oregon. The group welcomes programmers interested in all functional languages, including Haskell, Clojure, Erlang, OCaml, and others. The group has been meeting regularly since September 2007 for presentations, demos and discussions applicable to all skill levels, from newbies and experts.

==== Participate =====

There are many ways to participate in **pdxfunc**:

  * [[http://calagator.org/events/search?query=pdxfunc|Attend our meetings]], they are usually on the second Monday of the month. If you have presentations, discussion topics or activities you would like to see, please post them to the mailing list or mention them at the beginning of meetings.
  * [[http://groups.google.com/group/pdxfunc|Subscribe to our online mailing list]] to receive meeting announcements and notes, get suggestions of interesting events, and participate in technical discussions. You may post jobs and gigs for FP-related work within ~100 miles of Portland.
  * [[http://twitter.com/#!/pdxfunc|Follow us on Twitter]] for meeting announcements and notes.
  * [[http://epdx.org/groups/11|Join us on ePDX]] to tell the world that you're part of this user group and find others.
