Cave Johnson here, announcing that workshop support is live! To upload a workshop map, simply place the link into the "workshop link" field on the (new and improved) upload page, and the fields will literally fill themselves out! That's right folks, even our upload forms have AI (not really, but the search page, that's another matter). You'll still need to specify difficulty, and the tags might be a little sparse, but my engineers tell me that's 10% the effort for 150% the profit. That's what I call a good deal.
Now you may be thinking "But Cave, what if I want to upload my own version of the map but still want workshop support?" Well, now don't worry, I've got my engineers on the problem right now. Greg tells me they've got a handy little double-button setup coming for the view file page, so keep your eyes peeled for that. And if you need help keeping your eyes peeled, go ahead and buy yourself a handy Aperture Science Eye-Peeling device. Completely safe, as long as you don't mind never having eyelids again. Who needs to blink, anyway?
Right. That's it for now. Cave out. Oh wait, one more thing. If you come across any problems, that's not a bug, that's a feature. But go ahead and inform engineers of any unintended features so that we can make a profit off of them. Wouldn't want to be wasting any money. Right, that's it now. Cave out.
