Yes, on the side of every topic page you will see a list of the people watching that topic with their profile pictures and the total number of watchers. If you're not seeing this - then you need to upgrade to the latest version of Confluence Questions, which you can do at Marketplace.
Hope that helps.
I had the same follow-on question as Man Che.
When you visit the topic page, it gives you a total tally of watchers (E.g., "WATCHERS (39)"), but it only displays the graphical avatars of the first 12 watchers.
This to me is an oversight/shortcoming worth highlighting.
It's also quite cumbersome to have to hover the mouse over each avatar to figure out the names of each person (particularly if they have a default avatar logo).
So I feel it's definitely worth putting the matter on your radars in consideration for fixing/improving in some manner.
Perhaps a link to the complete textual list of names of all watchers of the topic?
In the interim, I learnt more about your rest api and figured out I can retrieve the list via this url (replacing <topicid> token below with the topicid you want to assess):
Figured this out via the documentation links below:
Is it possible to select fields via the confluence REST api? I tried something like the following:
...with the hope that it would retrieve just the fullName field, but it just returned all the fields.
Anyways, I'm content with this workaround for now, just wanted to provide further feedback to you, all the same.
