Freecodecamp: RegExp Restrict Possible Usernames challenge need stricker test

[minggas]

Describe your problem and how to reproduce it:
There's no test for the first check:
1) The only numbers in the username have to be at the end. There can be zero or more of them at the end.

That way the RegEx /[a-z]{2,}/i pass in all tests when it shouldn't, because this regex match any username who has at least two letters.

Add a Link to the page with the problem:

Thanks for reporting this @minggas - this is fixed in beta. However the beta site is down right now so the only way verify that it's fixed is to run the site locally - which I have done.

I can confirm that this issue is non-existent on the current master.
It will be updated as soon as the new version is live.
