Thanks to a blog posting by Liessa I got motivated to alter the fifonet.org site somehow. We now have a sidebar with channel quotes and a list of contributors.
I had to modify the plugin somewhat, because I get the plugins in RSS format. Here you can find the modified code in a tarball. Just drop it in your wordpress wp-content/plugins dir and enable it from the admin menu.
I also added some features so you can address the error message from your css. All modifications should be 100% backwards compatible with the original version.
usage:
<? if (function_exists(displayQuote))
displayQuote(); ?>
for normal usage. To use a non-default quote source, you can add a URL as the 1st and only parameter to displayQuote().
