A CCK content field which lets you add a country to your content types; displaying country name, ISO 3166-1 alpha-2 code, ISO 3166-1 alpha-3 code or a countryicon with module
Allows textfield to be rendered like a node reference, with some autocompletion magic on edits.
A university department wants to list the authors on their publications' page. Any given publication may have several authors, both from the department and outsiders, with their order being important (ie. it is quite likely to have an 'employee-outsider-employee-outsider' like order.) If an author is an employee of the department, his/her name should be displayed as a link to his/her own profile page, while outsiders' name should be displayed as clear text. There are several use cases with high probability here:
It is quite likely to have an author order like 'employee-outsider-employee-outsider'.
It is quite likely that a now-outsider author becomes an employee later on, in which case his/her name should automatically converted to a link to his/her profile without any changes to the publication.
It is quite likely that the site editor wants to enter existing authors' names without typos, regardless of that they are employees or not.
So what does this module do then, anyway?
Let's switch to Drupal tongue. :) Want to have a nodereference-like link to a node that does not exist yet? Want to have autocompletion both on existing field values and on existing node titles of other content types? Install and enable this text_noderef.module, and all your problems fly away!
You have several different pieces of profile information about your users regarding to their work, eating habits, leisure time, and so on, all of which are considered to be semi-private (ie. may be hidden from eg. unauthenticated users). You may want to make (some part of) their profile data merged into one node per user, possibly with some considerably different layout and/or access control. You have set up different content types: 'work', 'eating', 'leisure', and 'public_profile', all of them set up with Content Profile module--but how to merge the first three into the fourth?
Here comes profile_aggregator.module handy. Just select the source profiles ('work', 'eating' and 'leisure'), select the target profile ('public_profile') with the appropriate format, and let the users update their pieces of profile information while having Drupal do the merge part of the work!
