Can you please adjust section #Formatting and markup, bullet #1, to indicate how to notify a user using the at-sign convention, if the user has embedded blanks in their userid? The same thing applies to the Phabricator markup doc page. I tried using underscores as replacements, but that didn't produce a link. Mathglot (talk) 22:33, 28 March 2023 (UTC)

User has not account on Phabricator so it is impossible to mention (notify) him.
Phabricator user names cannot contain spaces, so if they decide to create a Phabricator account, they’ll need to decide what to do with those spaces.
Ah, thanks for that. Could someone please add a link to the #Formatting and markup section, linking to wherever it is in the manual where the syntax of a valid username is discussed, because I cannot find it.
