I had the requisite reputation for voting for close during the beta phase (according to the reputation page, my rep exceeded 500 on Nov 2, while the official launch was around Nov 11, when the privilege cap was raised to 3000). I distinctly remember exercising it once during the beta.
Now I noticed I no longer have the privilege.
[status-by-design]? I was under the impression that privileges are not taken away once they are obtained. Perhaps this has already been answered on meta.SO, but I wasn't able to find it.
