Thanks for retagging some questions in geometry tag.
@FrançoisG.Dorais I have noticed that the synonym topology $\to$ gn.general-topology has been created. Perhaps it should be in some way marked in the relevant post that this is the way mods decided to go.
I will also point out that quid argued against this synonym. (In fact, based on they suggestion the analogous synonym was removed on math.SE.)
Martin, I had read the discussion you and quid were having. I am fine with the idea of just killing off the tag if and when it appears. — Todd Trimble ♦Jul 2 '16 at 11:30
