Apologies, but I messed up with a duplicate new plugin submission
The correct plugin name is "CaptionPix" and the plugin url is captionpix.
Please delete the second submission where I included a space in the name.
Right now the first submission is showing at http://wordpress.org/extend/plugins/captionpix/ however when I try and check out the plugin using subversion I get an error:
svn co http://plugins.svn.wordpress.org/captionpix captionpix
svn: URL 'http://plugins.svn.wordpress.org/captionpix' doesn't exist
I presume that this is just because the request is waiting approval.
Thanks in advance and apologies for messing up.
