Welcome to PLUG

Celebrating over 25 years of Portland's best technical dialog and assistance

The Portland Linux/Unix Group (PLUG) is a group of enthusiasts dedicated to teaching and learning about Linux, Unix and related freedom-producing technologies. There is no membership fee to join and we welcome people of all levels of experience. PLUG has met since 1994 and hosts several mailing lists, a monthly General meeting, periodic Advanced Topics meetings, and a hands-on support Clinic. All in-person events are on hold until further notice. Other Portland-area tech community events can be found at calagator.org.

PLUG is open to everyone but does not tolerate abusive behavior on its mailing lists or at its meetings.

PLUG Mailing Lists and IRC

Between meetings, we converse on a number of mailing lists and IRC:
