You'll need to convert your bump lists to use semi-colons. It may be a pain now, but this is the first step to a much more efficient system that has far more advantages than the current system.
Hi John,
If someone (now or in the future) forgets to do a ; (semi-colon) and types , (a comma) instead, does that mean the second name will not be pinged? Ex: Bob, Joe instead of Bob; Joe
