[TYPO3] input Form help!!

[SKLIG]

I need to make a petition.

It will need the persons name, profession, location, and email.

I was thinking of trying to make a form, but a form sends a mail.

What I need is the input to be put into a textfile one entry on a line.

i.e.  myname, electrician, Doncaster, bla at bla.com
      myname2, doctor, Basel, bla at bla.com
      ETC.


Can this be done with one of your existing extensions? 

Please go gentle I am new to typo3

Cheers and thank you
