I really want to thank you for this module !! This is exactly the feature I've been looking for during the past 6 months or so!
I tried a lot of different modules before, posted questions in forums but found nothing truly satisfying. Out of despair, I almost started to code a module myself (I thought of grouping several CCK fields in a fieldgroup). Eventually I read a forum post mentioning Flexi-Field and decided to give it a go.

Basically, what I wanted was a list of publications with their contributors and an attribute to store the role of each contributor in the publication. Simple? I could not believe that nobody had ever needed to do that in Drupal.

Some modules provide a solution using an intermediary node to describe the relationship (the best I've found is Node Relationships). But that leaves me with thousands of 'fake' nodes that are not needed. Your solution is way much better for me !

The only thing I regret is that the module name doesn't do justice to the excellent work you have done. I would have overlooked it easily if it hadn't been for that forum post I stumbled upon, while doing a random search through all the Drupal modules. How about something like CCK Flexi Field or Embedded Content Field ?

Anyway, a really great piece of work. Can't wait to see it grow and provide more features. I am not an expert developer but if you ever want some help with this, I'll be happy to contribute.

Thanks again!
