This task is about making people aware when they've created – what looks like a ping – for an unregistered username.
=== Background
As the pinging feature is currently implemented, the username suggest list will "return" results regardless of whether the username the person searching for has been registered or not.
The username suggestion list behaving in this way, coupled with the addition of the `Find user:___` heading (T252084) could reinforce peoples' expectation that the person they are searching for has an account considering they searched for them and a "result" showed up.
This task about revising how username "results" are presented in the username suggestion list and/or how they appear within the `visual` mode's text input area so people know when they are attempting to ping someone who does not "exist" on Wikipedia.
=== Implementation details
=== Approaches
//The below are borrowed from T252084#6309510//
- **Approach #1: revise how usernames are presented within the //username suggestion list//**
-- Implementation: when someone initiates the ping feature and "searches for" a username that is not registered, the username suggestion list will visually indicate as much.
-- Consideration: there could be cases where people make a selection //before// the software is able to verify whether the username being searched for is registered or not.
- **Approach #2: revise how username are presented within the //text input are//.**
-- Implementation: when someone selects a username that is not registered from the username suggestion list, the user links that appears within the `visual` mode's text input area will communicate to people that the user they are trying to notify is not registered.
-- Consideration: in this implementation, the communication happens at a different step long the user's path, potentially meaning the effort to rectify the situation (read: revise the ping) is greater than had the issue been communicated "earlier."

- [ ] 2. What approach will we implement first?
