Many thanks for your kind words.

You can change the description quite easily, I've posted a note on how to do this at our website:

It's towards the bottom of the page, see 'Custom Edits'.
Should do the job for you, hope that helps. Remember to back up your site and DB first, this edit hasn't been tested yet.

As the author of Mad Blanks, I do recognize that it can be daunting to set up for some users. There are a lot of options because it can do a lot of things. Please, please, please use the forum on the Mad Blanks website to ask for help doing what you want to do, or to find out if it is possible with this extension. I have made numerous small custom changes to make things possible for Mad Blanks users. I need your questions and feedback so I know what the sticking points are to help make this a better extension. I am planning a wizard of some sort to help make categories and quizzes easier to create in a future release.
