Symptoms
The client is not able to share workflows when using the K2 Designer.
Diagnoses
There were issues with the "Share" feature in 467 and the feature was disabled there. (I have confirmed that this is working in 469)
Resolution
I have tested this in 469 and the "Share" options is working as expected. The client said that they are planning to upgrade soon and he will revisit the issue if need be.
