What plug-ins are you looking for?
There are several that are supposed to be installed with the program - in the plugin manager it shows Flickr, Canon tether, Nikon Tether and SmugMug, none of which show up. The one I've loaded - Zenfolio - shows up and I can use that. I've tried installing Flickr again by putting a downloaded plugin into the plug in folder I created for Zenfolio, but that hasn't worked. I'm using Mac OS X Lion which is a complete bunch of **** but not sure if thats the problem. I can't find any Lightroom folders under Mac os/Library/Application Support/Adobe and in my user flder there are lightroom folders but nothing to do with plugins...
Hope you can help because I can't seem to find anyone else who has this problem
Publishing plugins may or may not also support reglar export.
