It's gr8 that u have the Bulk vs Chat option. It would b even better if u added a 3rd option that allows users to decide, when composing a msg (b4 pressing send), if they want replies 2 b sent to everyone (chat) or just to them (bulk). I've sent group msgs but forgot to turn off chat and ppl complained (understandably so) as it can sometimes be numerous responses. Unfortunately, in cutrent state, the sender can't do anything to stop chat replies once msg is sent. Just think... if u are the 1st to create such an enhancement....standard/trend setter.
