Is this a plug in or is there a setting somewhere? I did search this forum for threads but didnt find my answer.

Thanks in advance.

it can be tempramental and is part of the core - I have found typing lowercase and then @ChurchOfPop but typing the username slower than normal and stopping before the end allows the userlist to appear, which allows you to then select the members name to mention.

Ah OK, thanks.

However, i noted that since the last 2 or 3 releases the trigger of the mentions seems not to work, to select a name.

Sometimes i need to remove everything including the @ and then start typing the name in order getting the userlist.

‌If I type slow the list of names generate. I hope it's not a limitation and it's a feature that can be improved on.

I'm also finding it impossible to get mentions to work on FF, chrome is absolutely fine.
