Since the Memorial partaking numbers have been going up year after year the GB figured they send out this message of understanding to stall the continued flood of professed chosen ones. They hoped the number would be reducing but that's not happening.
Here's some Memorial partaking figures:
2008 - 9,986
2009 - 10857
2010 - 11,202
2011 - 11,824
The 144,000 slots should have been filled up by now.
