Just wondering, is there an option when creating a virtual cache to make the finder answer a question correctly or enter a certain word to complete the find like in history caches?

When you have created your cache page but before you publish, on the right hand side there should be a section like this:

Owner Actions
Edit this Cache
Questions and Answers <- Click this
Add/Edit Gallery
Clone this Cache

Thank you kindly. I see it now.

and do you know how to delete it!

Is that a statement or question? Yes you can remove it. Go and edit your QandA and on the right hand side tick DELETE for any QandA set you want to remove.
