I work at a small to medium size logistics business and would like our visitors to sign in without having to go the pen and paper route. I'm thinking of a slick application visitors can type their name, who they are wanting to see, and what business they have with us. I know there is software I can buy that can manage this type of thing for me, but I would like to create my own. Any ideas on how I can begin? What programs are out there that can allow me to do this for free?
