This has happened twice now - I get the "red dot" on the "Review Queues" icon, but when I click on it the queues that are available to me (my rep is about 750) are all empty, though there are some greyed-out queues that have as many as 200 items. Am I getting notified by mistake?
Edit: To be clear, this isn't any big problem for me, but as the event queues are new to me (I guess I passed some reputation cut-off) I've been spending a few moments trying to figure out what/if I'm missing.
