Topic #1: What have you found the most interesting about written interrogatories?

Topic #2: Each set of Interrogatories has to be numbered. If I propound Set No. One, and only ask interrogatories numbers 1 - 5, Set No. TWO will start with number 6. What are the maximum number of interrogatories a party can ask? Is there a way around that?

Topic #3: Who keeps the original document of the interrogatories who maintains the original responses?

Topic #4: If the responding party does not provide a legally sufficient response to interrogatory, you need to file a Motion to Compel Further Response to Interrogatory. What process does the propounding party have to engage in with the responding party before they can file the moving papers and what is its purpose?
