Sketchbook: And why are they not burned?

Perhaps you've heard of the Worldwide Indexing Event. It's a great way to get involved in family history. Here's how the event is described on Facebook: 

"Join volunteers from around the world to help “Fuel the Find” August 7-14 (wherever you are). You will have one week to participate by indexing at least one batch in the language of your choice. If you are fluent in French, Italian, Portuguese, or Spanish—our focus languages for 2015—please help index records in one of those languages. Special training will soon be available to help you prepare!
"Here are some suggestions to avoid a possible system slowdown: download indexing batches ahead of time and work offline, avoid Sunday and Monday evenings, and invite new indexers to install the program before the event starts. 
"Invite a friend and join us for this record breaking event!"https://familysearch.org/indexingevent2015
