Some dings mean more than others. Across all my alts, I've heard the noise and seen the yellow flashes over
two hundred times -- yet few of them are memorable. I find odd-numbered levels particularly boring, as nothing really
happens (some armour and quests become available, but even numbers are where it's at).
However, some dings are memorable enough to make up for the monotone of the majority. Hitting 60 (see right) isn't an experience most of us forget; my first "big ding" was at 40, after beating up some STV gorillas for those last few XP. What's your best ding memory?
