This UX looks odd to me.
A login button under a vote count?
To a new user, not logged in, it’s not clear the figure is a vote count.
I think it should just say “vote” or “votes” if you click it, and you’re not logged, it should prompt a login. Other forums work this way.
I’m not sure if this is something this particular forum has come up with or if it’s configurable in the plugin settings
