Ok guys, I need some opinions and help on this one.

So, I have a command button, that when pushed prompts you with a yes or no box. If yes or no is pushed, I want the data (yes or no) to be stored SOMEWHERE on the internet where i can access it, and nobody else can. I want it to add a new line to a text file on MY ftp site. So lets say 5 people have the program. They all choose yes or no. I then want to see my updated text file with the contents..

Yes
No
No
Yes
Yes

.. I want a new line added with a Yes or No (Depending on the answer the chose) in this ONE file located on my ftp whenever another person chooses yes or no (A person can choose yes or no however many times they like).. How can I do this?

Thanks.
