Why would anyone want to keep using it after they graduate? It's an abysmal system that works poorly. I hope to high heaven they decide to farm it out to Google to run.
On that note, has anyone here configured Webmail to not only forward all email to Gmail, but also configured Gmail so that it "sends" through Webmail? (ie. I want someone to email me at my @iastate.edu, have it automatically sent to my @gmail.com, read it, write a reply in Gmail, hit send, and have the recipient see that it's from @iastate.edu.)
