Since there are now new guild achievements, I'm sure you've all figured out the great question that faces our generation. That question, of course, is 'how do we respond when a guild achievement is earned?' I'm sure some people will be fine just going with 'grats', as that is the general achievement norm, but that is a bit awkward to use when the achievement is earned partially by you. Given this then, I propose:
When you ARE NOT part of the group that earns the guild achievement: "Highfive!"
When you ARE part of the group that earns the guild achievement: "Self-five!"
I believe this terminology will convey the proper emotions and reinforce the team spirit inherent within any good guild.
