Hi John,
> Needs an rssx /stop command.
Great idea! (oops)
New (beta) version is attached - the only change is that it now
supports "rssx /stop" to clear the RSS queue and end processing.
Has anyone found an rss feed that doesn't "work" yet? I've been
digging, but nothing yet (except that one by the w3c "web standards
body," but who expects _their_ stuff to work, anyway? <g />).
Regards,
