I recently started working at a non-profit Seniors Center. They have a database a volunteer from the local university made for them but it's hard to use and full of error messages when trying to do simple things. I'm looking for a low or no cost alternative to put in place here. Since the majority of workers here are seniors with a low to medium knowledge of computers it would be great if the database was really user friendly. We need to keep track of things like members, donations and room bookings. Any suggestions?
