Recently, I mentioned that I worked with Claude Code to add scripts and changes to the drummerCms Github repo to be able to build a local copy of an oldSchool blog from a Drummer OPML file. In conversation with Frank McPherson, he asked if the web-based outliner from Dave Winer that I modified this year could support editing a OPML file for Drummer oldSchool blog use. This morning, I was able to add outline elements matching those in an oldSchool blog OPML file and was able to build a new local copy with those changes correctly rendered.

Based on this testing, I believe my OPML outliner can support oldSchool blogging use, with some inconveniences (having to add other outline elements used within oldSchool). If anyone is interested in collaborating on updating the outliner UI to support oldSchool blogging, let me know!
