I only have just over 2K rep points here, yet I can see answers others have written and deleted. Is that intentional? Or is it a bug?
ELL is a beta site, so the reputation level at which you earn privileges is decreased. 2k is exactly the right threshold for the new powers you're talking about :)
You can check out the modified privilege levels here, and see what you've already earned and when you'll get more in the future!
