When I go to the mykeys page, I can see my (currently not activated) key for alpha. When I clicked it, I noticed that the text box showing my alpha key actually allowed user-enterable text. Is this intended, and if so, can I use it to change my key to any combination I want prior to activation? Also, will performing the Steam convert change any of this?
The text box is there to make the text easier to select and copy. You could try changing it, but odds are it wouldn't be a valid key then.
