Ask and ye shall receive. Now I have to admit my failure of reading comprehension, as I did not grok from Dave’s explanation a week ago that the Multi-Author Weblog tool has exactly the feature I wished for in my previous entry.
Mark Paschal, ever helpful, commented thusly:
Autoposting from feeds is what the Multi-Author Weblog tool is for. Since you have a paid LJ account, you could use a special style (that’s the one I put together, but I know l.m. orchard had one too) to get RSS with item bodies.
Oh frabjous day, callooh, callay!
