Project 1999 - View Single Post - Green guilds by the numbers

I don't know how useful this will be, but it was the right combination of useless + fun for me to put together. This is a little messy and I possibly did the parsing wrong, but if this does what I mean it to, for every guild name I've seen since launch, it should show the time at which I first observed it. This might help fill in some blanks for dead guilds?
