Today an user (I can't remember his username) have posted two interesting questions in the Commutative Algebra section, but these were not very well formulated, so he got few downvotes. Then he deleted the questions and I wonder how can I find (if possible!) these questions?

Edit. Maybe this helps: one was about the Rees algebra of an ideal, while the other one was about the edge ideal of a graph.
