okay, I've been wondering about this for a while now... and it's such a small thing, but not knowing is bugging the heck out of me. So while this may be a stupid question, I have to ask... where do the reputation tags come from?

Just so everyone understands what I mean... when you hover your mouse over the little green blocks that represent your rep, a tag appears with a little...not quote, but saying in it. And the tag changes. For example... when I hover my mouse over my rep blocks, the tag says 'I'm known to All'. The tag before it was that I'm just really nice. The very first one said that I showed promise and would go far.... or something like that.

Are these preset tags? Or are these tags guild members are leaving? How do the rep tags work?
