Actually, supporters used to have blue usernames a few months back. Kinda like the mods, but in italics rather than bold letters.I was so excited when I could become green. My dad donated for me, after I nearly begged him to do so. XD I just couldn't wait any longer to enjoy all of the unique features that supporters get. <3 So, I was even more excited to get it. I was literally screaming lol. I've adjusted quickly to it because I wanted it so bad.
It's fun to be green and not feel like some n00b who just joined PC, especially when you were here in 2004. lol
At one point, after the Assistant Admin and Admin usergroups were merged, green usernames weren't in use anymore. (They were the default username color for the Assistant Admin group).
So the supporters essentially gathered up our ranks and launched attack on the tyrant administration (we petitioned really really hard and did polls and other fun stuff yay). So eventually they gave us the long awaited green username!
tl;dr this thread is about the change between blue and green usernames, not becoming a supporter :p
I'm happy you're happy, regardless.
