I have a form that will be filled out by a systems person and submitted to a library. One this is done a workflow notifies 20 users and asks them to fill in their piece of the puzzle. They basically click in an area pertinent to their position (e.g. Network, Help desk, Development) and update a couple of check-boxes and a free text field and then submit their changes. Authors are overwriting each other as items are submitted. Check in and check out would likely solve the problem but some non-technical users are not adopting; others don't check in. I thought I'd send out a workflow task and make it serial, but vacationers hold up this process. I also tried the auto check in and check out method using rules but it is not working for me. Any technical ideas, behavior changes or otherwise are welcome. Thanks!
