We have multiple people working on our organization who have the same first name. Typically, when a new person with the same first name joins the organization, they will choose a Flowdock name like "FirstnameLastinitial". We recently ran into a situation where someone chose the same Flowdock name that someone else already had, and Flowdock allowed it. We have since run into issues with both people using that name receiving the same notifications from other users and getting errors saying they need to change their names. Is there not some way to prevent this from happening in the first place?
