It looks like Production.cls is a production class which is loaded into and compiled within the IRIS data platform.  You would need a connection in order to load and compile the code.  I am not sure what you mean by compiling the code (which required IRIS) without a connection to IRIS?  Can you please explain more about what you are trying to accomplish?   

This was more to figure out the proper way to do this in order for tracking for the badge, etc on the G.M. platform.  It makes sense that it needs to originate in a challenge (and than you to Olga for pointing that out).

I don't think that just having a form on the D.C. to invite a friend necessarily makes sense, as anyone can just shoot a friend an email with the link.  If others would like to see this as a new feature I won't object though.

@Julian Matthews  - it is never too late :)  Since you know the exact version that you were upgrading from / to, I think you're in the best position to still report this as a bug to the WRC.  They can then test to see if it's still an issue on the latest versions and they can log an internal bug if that is that case.  I would encourage you to still take a little time and ensure it is officially logged.
