Hi. all..
I've added some simple description about how to develop ngrinder plugins.
http://www.cubrid.org/wiki_ngrinder/entry/how-to-develop-pluginAnd.. also I've pushed the siteminder-sso which our company(Naver) uses.
This allows the new users be able to use ngrinder without any registration step if they are already passed by siteminder SSO. It's increased the usability of ngrinder.
