How to create a Custom Content type without Title? I'm trying to make an auction website. Therefore I made 2 Custom Content Types:
1)Item for sale
2)Offer(Bid) from user(with node reference url to Sale item)
I need to receive only 1 field(Price) from the user while making a Bid (creating the second content type).  

I deleted the 'Body' field from my Content Type but I could not find a way to remove 'Title' field because it is mandatory(required) field :(
The user that makes a Bid(offer) has nothing to do with Title (he doesnt need to know that he's creating a content)

How can I remove the 'Title' field?
You can use the Auto Nodetitles module.


  "auto_nodetitle" is a small and efficient module that allows hiding of
  the content title field in the form. To prevent empty content title
  fields one can configure it to generate the title by a given pattern.
  
  When the token module is installed it's possible to use various node
  data for the auto generated title - e.g. use the text of a CCK field
  (since 5.x).
