I came here to find out how to tag someone in a forum response. Since the video doesn't mention how to do it, here are the instructions (kindly supplied elsewhere by Alison Field)

Either copy their shortcut [name] as it appears at the top of their post by placing your cursor just after it, dragging it till the whole name is highlighted then click Ctrl+C (this is a bit fiddly but works) then paste it into your reply.

Or type @ followed by either their whole name without spaces or capitals or (if their first name is common) just their surname.

Brilliant, Emma Goldsmith,

Thanks for spreading the love!
