Communicate frequently. Keep asking people for help and make sure you know what you're doing. Even if you don't, just ask for help. Always make sure you're communicating with the team, regardless of whether you're confused or not because you need to make sure you're getting the work for the experience. Keep your online presence available as early in the morning as you can (i.e. logon to Jabber in the morning, even if you're still getting ready) so people know you're available to talk to if need be.
