@DavidRoberts I try not to edit too much. (I suppose you follow meta closely enough to know that some users around here regularly complain about bumping. Considering that there are hundreds - maybe thousands - of dead links, I mention dead links more often in comments than directly editing them.)
Moreover, since you have provided the "old" link (from settheory.mathtalks.org), it's possible that you know where is a new location for that link (if there is one).
Of course, if somebody else is willing to edit dead links, I have no objection to dead. (Some possible candidates can also be found in this room.)
>it's possible that you know where is a new location for that link
No, I apparently edited that a while back, I don't remember where I got it from (possibly just the other answer!) I like to add stable links, and I think the DASH one would be pretty stable.
I think that bringing back old interesting questions and answers now and then is not a bad thing, just not a huge flood of them. It certainly is good for the asker/answerer, who get a second chance at some upvotes.
Needless to say, feel free to edit them further if needed. (The question has been bumped anyway, so MO users are less likely to object to subsequent edits.)
