Topic: Good news for those who can't run the Unity Drydock
If, like me, you can't run the Unity Drydock because you use Linux, or if you simply don't have access to Excel, I have good news. The version of Excel in MS Office Online seems to run the Drydock just fine. I have not tested it completely, but the "error 502" I was getting no longer appears, and so far it seems to be working as expected. Give it a try - it's free, so you have nothing to lose! Instructions are here:

The instructions on the above page will work for you whether you run Linux, Windows, or Mac - it's all the same since you run the app in your web browser.
Go forth and build!
