For some reason madglee got left off the trophy holder thing and he's probably way more active than solostrike at least.
While logic would dictate that you could get one purely through story writing, we all know that's not how the real world works! Lol. It's partially up to how the trophy holders feel about you. (And yes, some of the other important stuff comes into play as well)
Honestly, there is no real hard set rule. Seth gave his trophy to Drakilian just for his forum posts and he never wrote anything. JJJ gave ugilick his trophy just for winning some treasure hunt forum game and again, at the time ug hadn't written any stories either.
That being said, Mizal is probably the next closest to gaining my trophy, since she's actually gotten up off her fat ass to write, one of which is actually feature worthy. Along with providing a lot of writing advice and helping noobs.
However, she fucked up so that's sort of up in the air now.
If MinnieKing actually had some better stories, he'd definitely get a trophy, considering he's written 8 of them along with making the effort of all the story comments he has. He's generally not an asshole either so you can't say the guy isn't trying.
