For example, on WhatsApp, use the whole 25 character limit for profile name. Examples:
Bob Moved To Signal.org
Alice MovedTo Signal.org
CharlieMovedTo Signal.org
Say Signal.org, not Signal, because they won’t know it’s an app.
Use your about section too. Same on Discord, Steam, Instagram, etc.
i can see how this would be an interesting function. sadly, we’re, nowhere near an end user ready experience in any non corporate messenger. it very much still depends on how tech savvy the user and how good the admin is. until that changes I’m gonna unilaterally say no to reinventing any wheels and say fix the stuff we have before adding more functionality.
