If I search "Grails" from the home page, I get this link to a Grails - user forum:
http://n2.nabble.com/grails---user-f1470603.htmlwhich says it contains zero threads.
If I search "Groovy" from the home page, I don't get links to the user or dev lists. Also none of the threads returned are from the Groovy or Grails lists either. So is your search index just messed up? Or are the email lists still being tracked by "old nabble?"
Thanks.
