What was that one setting ... I Think it was Interactive Sub Prompts... setting it to "Yes"...
Would that prevent somone from getting spammed with messages after completeing a script or whatnot?

No - ISP on just allows messages from some locations where you normally won't see them with ISP off. ISP off is a bad thing in many players opinions.

If you're on dock and there's a bunch of fighits during the time, then you lift... it sucks. ISPs off mean that at various prompts you don't get certain things.

Perhaps the biggest impact in today's play is w/ plock. You do get the "fighter lock is decaying" message and can drop on that, however you don't that until after the fig is taken out... which is rather late in the process. With them on you get limpet activated msgs too and can trigger on either them or the "enters sector" message... both of which mean you can land on someone and trap them in your IG.

In an unlim this is one of the only ways to kill a smart gridder, which means that without ISPs on it's very tough to make plock work.

In a turns game... IMO it's not quite as important.

When in doubt turn them on. There's really no reason to not have them on.
