[Plugin: Shuffle] Plug in DOES not work

With all due respect, if you develop a plug-in and publish it on the ww.wp.xz.cn site for others to use, it would be appropriate to provide a little bit of support. I had to dig through the site to discover the code snippets that have to be inserted into the loop. After having done so, the plug in still doesn’t work. I have posted this question to the forums hereand to the developer’s blog as well, but no reply has come from him.
If you are too busy or unable (or too cool) to provide any feedback to your users, it would be better if you did not publish your plug in on ww.wp.xz.cn.
