Remove or Double the limit of whatsapp users in a single group chat
Hello Facebook, we had a situation here in chandler, AZ where teenage kid gone missing for almost a day before we were able to find him on a Metro Rail station about 25 miles away from home. This was all possible because of the friends coming together with absolute commitment and great team work on the whatsapp application. Can't thank enough local police authorities for their support to the family in finding the kid and through out the process.
The one short fall from this pain full endeavor was not able to coordinate with large community of people on one single whatsapp group which currently limits to 250 people.
Humble request is to consider the case studies like this and help us for future incidents (I hope we won't ever see these anymore) to eliminate the number of users in one single whatsapp group chat or double it up. This will eliminate creating multiple whatsapp groups and don't waste the precious time we have in finding missing people.
Thanks for your consideration.
