Well, "all" is easy as you mention. But I do not recommend it.This actually sounds pretty cool. I would naively assume that letting users see who is hogging up the testbed would lead to self-correcting behavior, but I'm guessin' something different happened. :-(
Well, I think its that Utah hosts such a wide variety of users, with many students from lots of institutions. We stick to the conservative (paranoid) side of things. I suspect that some sites could open that up (via another sitevar) and be fine. Depends on the user base. We take back diffs ... Lbs
