I noticed some profiles on Dan's site were outdated. How do you keep track of who is still at this adress and who is not at this adress anymore etc? Unless the person updates his profile there is no way of telling if the information he/she posted is still good and that makes the quality of the chaser database go down. A idea would be to send out a e-mail every year and remind everyone they still have a profile in the storm chaser database. That means more work though.
