Reply "Collision detection"

PerBonomi Your code is suggesting that this component will only show to a super user if other super users are responding to the same topic.

Wendy_S Your screenshot though suggests that it will show to super users if any community member is responding. Is that correct?

I actually favour the variant where only SUs see other SUs responding as the second variant seems quite intrusive to almost the level of monitoring members' behaviour. Also usually the SU's / staff's worry  most of the time seems to be to respond to a topic another SU/staff is responding to and not necessarily normal "mortal" members.
