Given the flexibility of using just raw numbers, I'd think it makes more sense to just use numbers and allow guilds to define the priorities internally themselves with an officer post or something.
Giving the sticky priorities names could be something I implement in the future, but it wouldn't be a high priority at this point.
So how about just displaying the priority next to the Sticky option which was part 2 of my post? It would be beneficial to see the priority a post is currently stickied at for those that can sticky so we know if were stickying something in with the right priority to make it appear above something else.
If you hover over the "Sticky" icon, it'll tell you it's priority. I'm in the process of using better tooltips than the browser built-in, but at the moment, if you hover over it, it'll tell you in a second or two.
Wait, I misread that. Yeah, I can show the priority next to the checkbox. Sure, I'll stick that on the list quick.
