Is there a feature where one user, whilst commenting, can tag another user who has already commented to a particular thread? If not, how can I achieve such a plugin?
We don’t have this feature currently.
This is another great question for our dev community: https://github.com/coralproject/talk/issues
As a feature, we would definitely want it to be opt-in only. (In other words, nobody can be tagged unless they activate the option in their profile - otherwise tagging users can be a way to flood people with notifications as a form of abuse and harassment)
Thanks for exploring Talk!
