Hint for Radio IM: deHTMLize an item with string.htmlToEmail.
Update 4:26pm: Jeremy Bowers explains the sociopolitics of HTML in tcp.im. My post was a quick missive about how I improved the stock news responder: change local adrstory^.storytext in line two of tcp.im.builtinResponders.news.script to string.htmlToEmail (adrstory^.storytext).
Since the news script isn't of very much practical use, it's not that important--but messaging "news" to markpascblog on AIM is marginally more useful than any that didn't make that change.
