no, that was me. i did not setup a watch script or anything to see how long the link was up for. but when I first tried it, it was active, and when I tried it the next day around the same time, it was gone.
Another way to look at it: the verb doesn't magically grow together and apart if you use it in different tenses (past, present, future). "I am setting up" (present) is two words - therefore the "set up" in "I set up a script yesterday" and "I did not set up" also needs to be two words.
Looks like the commonality is that the second word in the pair is often one of (in, out, up, down).
