You have to wait a 30 days then you can change it

i know that
but i'm not counting every single day
so i don't know when it's been 30 days

Imgflip hasn't put the "cement" to the gap yet, then you have to not feel the time for changing your username and send feedback including the suggestion.

whar

1. Don't feel the time until you see that the "Previous username:" thing under your current username is gone, then you can change it again.
2. Tell imgflip your problem by "Send feedback" in imgflip.com main menu and suggest if they can add a feature that fills the need.

1. I already know that the previous username disappears when you can change your username
2. This stream is specifically for suggesting features and stuff they could add / change

If you want an imgflip web developer to add a feature that make you knowing how much you have to wait for next username change, then leave this post here until a web developer replies you. Closing the discussion.

That's what I'm doing.
