pdx.social is now running 2.9.2. You have to go into the prefs and disable the "advanced" UI if you want the single-column mode. I like it!
pdx.social is a server for folks who live in the Portland, OR region. Registration is by invitation only and you can receive an invitation by contacting a member or emailing firstname.lastname@example.org. You must abide by our Code of Conduct.
