Erwin sharing and merge changes among multiple data modelers

We have 4 data modelers working on the same Erwin file and we are 'sharing the pen' by rotating the file to each other to incorporate their changes.  To make things less painful we use the compare function, but it doesn't work well for us coordinating at all.  

Is there a way or tool to work with Erwin with multiple users?  I know that there are APIs available, but we are consultants working on a tight dealine, hiring developers just to do that is out of the questions.  

Any help will be greatly appreciated!  Thanks.

There is special Workgroup Edition  of the Erwin software, allowing the processing of the same model by the group of developers.
It has the followin features:
Concurrent Model Access With Optional Model Locking
Multi-user Collision Resolution
Independent Model Merge
Version Management
Repository

Details about the product:
http://erwin.com/products/detail/ca_erwin_data_modeler_workgroup_edition/

It's more expensive, than the standalone version, however, it's native powerful solution for the collaborative work.

What version and Edition of Erwin are you using.?

Erwin Data Modeling Workgroup Edition has the feature that you are seeking although there is a cost associated.

Would you consider a different modeling tool (ie Freeware)?

The Erwin is 7.3.11.2812. It is not workgroup edition.  No not another freeware modeling tool, unless we can import and export between Erwin.  One of the modeler suggest to hire an 'erwin consultant' to do that because erwin provide APIs to do the job, and no I don't think it is a good idea.  It is just for this one client, so I are not going to purchase an expensive software which the client is not going to pay for.

I would agree with your assessment that to build the functionality of the workgroup edition using the API would be a waste of time and money.

Have you inquired about the cost of upgrading to workgroup edition?  I believe there is a bundled package with workgroup and several developers combined.  Maybe cost effective.
Next best idea may be to levage some of the user forums to find someone that has WE and not currently utilizing it (ie allow you to lease their license).

But there are also Linkedin, Facebook and other social media sites specifically for Erwin
