I want to edit Prove an identity about $\iint_S\mathbf{r}\wedge d\mathbf{S}$ using Stokes' theoremProve an identity about $\iint_S\mathbf{r}\wedge d\mathbf{S}$ using Stokes' theorem but the edit link is greyed out and non-functional. What's up?
Update: Someone else edited the post, and now I can, but why was I locked out before?
