Here at GUADEC until Wednesday morning.
Last week I made a nifty hack for sending email into my ZWiki installation. I often find myself writing email with ideas I want to preserve, or point other people to at a later date, and unfortunately you can't rely on mailing list archives, they tend to come and go.
You can find the hack here: EmailToZWiki. I used the 'log' field of ZWiki to put the first 150 or so characters of the mail -- this can then be extracted via an RSS feed, like this one from my wiki. (Googling for 'RSS and ZWiki' yields reasonable results for adding RSS to ZWiki, as long as you figure out you need to Catalog-enable your ZWiki.)
I used WebDAV to get the content into my ZWiki. You need to have a trivial PUT_handler in your ZWiki to make it set the type of new documents properly. Again, Google is your friend here.
One day, it'll be simpler :)
