Sorry if this is obvious, but I’m rather clumsy with web things.
When there are new posts in a thread, there’s a blue dot with the number of new posts written in it at the right of the thread title. I click on it, I’m whisked away to the earliest of the new posts. Fine, I get that.
But sometimes the dot isn’t blue but gray. When I click on it, it takes me to a post I’ve already read.
I’m thinking gray dots point to existing posts that have been modified. Is this correct?
