Opps! sorry, buddy. The site is http://maythil.com, where blogs are dedicated to quiz.

Further, some time back, I had come across a multi-quiz software package, which I was able to incorporate into Joomla. With Elgg also it must be possible, I think. Only I have to locate it. Google for "Free quiz software"; maybe you will find it.

Why not "locate" that multi-quiz software on *your Joomla and post back here ?

Dhrup, It is very very complicated. It's a bulk software as of my last checking. It's meant for creating a host of tasks. Picking juste one (like a quiz session with multiple answers) is not easy. I hade tried it twice and given up the idea at Joomla. Have not tried the generic PHP version (if any). I will revist the scene again. :)

Have you looked at the documentation here: http://docs.elgg.org/wiki/Misconfigured_plugin_error ?
