@MartinSleziak In both questions, I have added pr.probability as the top-level tag. (I hope it is at least somewhat reasonable. Maybe adding mg.metric-geometry would be a reasonable way to do - I'll leave this to more experienced users.

@MartinSleziak I waited a bit to see whether I get any feedback on this here in chat. Eventually I created both specific-user and deleted-accounts.

Of course, if for some reason you think that those tags are not going to be useful, feel free to remove them. (I tried to point out above that they are used quite often on another meta.)
