The URL could display the user's ID instead of the username.
Just like the store. For example:

[blue][b]Instead of [/blue][/b][red]https://ReeliChat.com/user/profile/(username)[/red], [blue][b]what about [/blue][/b][red]https://ReeliChat.com/user/profile/(person's id)[/red] [blue][b]or[/blue][/b] [red]https://ReeliChat.com/users/view?id=(person's id)[/red]

That would be better.

I kinda agree but it could also be like www.ReeliChat.com/profile/lilboi97/45673

Much easier to find people without their ID. If they don't put their ID in their profile, its really hard to find out what their URL would be.

There is the user search
