Downside is that everything is done with keyboard shortcuts. For example, to bring up the editor you press (Windows Key + E), browser (Windows Key + W), File Manager (WK + F), to bring up log off options [shutdown/log off/restart/etc](WK + X).
First off, double post.
I know we make that mistake every once in a while, I'm just warning you.
You don't need to warn, you just politely point out that it is considered a bad forum practice to double post. Warning makes it sound like you are an admin or moderator getting onto them and ready to ban them for a minor thing.
