The link to "A+ Snack Mix" on the page at: http://www.extension.org/pages/Famili... does not work.
It probably has to do with a bigger problem than just one bad link ;(
Thanks for the report, we've asked the content provider to rename the page. And we have marked it as a bug - but it's going to be a bit before we can really sit down and address it.
It has to do with the hoops that we have to jump through with mediawiki articles being named with titles that include a '?' character in them. MediaWiki itself will use the title as as the text in the URL (which is great because it's better for search engines) - but unfortunately has you start to take that and pipe it through other applications (such as our public site), it gets a bit challenging to maintain. Questions as titles are very important to the content providers, the URL less so, but the URL is very important to maintain for links and search - so we are going to have to rethink the problem again and figure out some way to deal with MediaWiki's design as a endpoint for the content that we are just using it as a source system for another application doing published content display.
