How to make fields available to users in Drupal 7? I want users to participate in creating some content. I allowed them (people/permissions)  to create own content on particular content type. The question is: how to provide them access to fields of content type, that are available to me as administrator? In other words, I can put content in fields through my admin panel, but how to make users possible to meet that fields, how to make fields  public?
Thanks in advance!
Give "Create content" permission to the user type who can create content at your instance.

There is the Field Permission module which lets you specify permissions for each field in a entity. You can set permission for each field by help of this module.
