Okay, it worked again here, too.
The cross-posting to LJ worked fairly well, though I’m not keen on the fact that I have to go in and manually change the LJ icon on the post rather than doing it through the plug-in; that was a definite plus to Live+Press. It’s a shame the writer of Live+Press didn’t keep up his work.
But now I’m all upgraded, and with less trouble than I thought I’d have. Now it’s time to play with other plug-ins.
