@zogstrip I can’t upgrade without the rebuild now (there’s a docker\_manager upgrade to do so the rebuild is mandatory and I have to wait tonight to do that).
I was wondering if you even fixed the error that appears when trying to type a username preceded by `@`
A message icon appears before the username (why?), no list of users appears when I’m typing.
I’m still on v1.9.0.beta11 +33 and all works well (no errors) until I type usernames without `@` otherwise I get the error “There was an error changing the ownership of the post”.
I see that the message icon appears even when I try to add users in a group if I type `@` (The requested URL or resource could not be found.)
Imho, adding usernames without or with `@` should be allowed the same way, with no errors.

I did not fix that. The 📧 is used to designate an email address. I think it’s a bug since it’s should at least have one character before the **`@`**.

@tgxworld shouldn’t this regex be something more like `.@` or `(?!^)@` ? i.e. requiring a non-empty local part for the email address

Good point. @nbianca Could you have a look at the regexp used here?

Hi @tgxworld,
I submitted [PR #5804](https://github.com/discourse/discourse/pull/5804) to fix this.
