I managed to delete 21 of the last 25 comments to WikiProject Oregon postings. The affected range is from 28 June 2008 through 21 July 2008.
I have the text saved, and
am investigating a workable way of resurrecting it. Sorry for the inconvenience.
WordPress’s technical support was responsive. Alas, deletion is forever. Another wiki-spoiling: I expect that everything which was ever there is still somewhere. As recompense, I’ve given myself 20 lashes and re-posted the comments. I apologize for decreased formatting, but I’m pretty sure all the content is present.
