Quite an active topic lately, many are confused by this add-on, and there is very little information explaining this feature. Several threads are already going off-topic discussing this, so I'm opening this topic to combine everything into one discussion.

So, for example
Obviously, starting this rating and voting is only possible for the privileged, admin, mods, president, and vice (I'm not sure how many other similar titles there are). But
How is it decided which thread gets the star rating?
Why is it partially and unclearly established who can vote? I voted once or twice by accident, while later in some other threads when I consciously tried, it was not possible. So it's not always only the rank that matters to be voted.
What exactly does this rating represent? Is it the quality of the discussion, the design, or the popularity? This is twisted to me, because for example threads from the signature campaign have this rating, and honestly there is no discussion there. I imagine that someone from the outside comes and sees the 5-star rating, and inside there are only applications for the campaign and announcements by the manager that the payment has been sent.
If voting is limited to specific members (admin, mods, pres, vice etc...), I will call them senat, I assume there are a few of them. Then why do all the other users need to see the rating that was decided by a very narrow circle of people? The impression is that a rather centralized opinion is imposed on all users of the forum.
OK, it's possible that I don't see all the details about this, but that's only because it's quite undefined and leaves a lot of room for free interpretation. I think it would be useful to publish the rules and conditions for the star rating feature somewhere to avoid misinterpretations.
