database

i need to have an e-mail exchange system and associated database created. it needs to allow two people to come together via a volley of e-mails, 10 in total. example: someone visits the website and decides they'd like to participate. they would enter their e-mail address and the e-mail address of the person with which they'd like to have this exchange with. this first person would then fill out a word limited text field and hit the send button. once the second person receives that e-mail, a link would direct them back to the website, open a page that contains the data for this particular exchange, and allow them to fill out another word limited text field. a similar implementation of what i envision this to be like is found at: [login to view URL] in the above example though, two people come together to play a game of chess. the respective moves are sent to each player via a link through e-mail. i would need the data stored in an admin accessable database where it is organized by various topics, date, title, rank, length, user, e-mail, etc. i want to be responsible for the design and look of the website so a close interaction with the programmer is necessary as i'm sure to have questions because i'm not the most technically minded. thank you.
