This is something that computers are good at - it shouldn't be a manual step. A "Do you realise that the submitter is an admin at the site, and do you really want to direct the ticket there" warning might be useful.

The other thing I found somewhat annoying is that when one of our machines crashed (twice) last weekend, I put the site in unscheduled downtime - but still ended up with a number of tickets. Some flag in ggus warning the submitter that the site has a known problem would be useful for the submitter as well I think.
