Solarshadow and creativename are both huge contributors to contest culture, but I don't know that they were huge parts of the board itself. They deserve recognition for their achievements though, for sure.
They're first ballot Hall of Famers, but not Mount Rushmore.
TRE is another guy who deserves a shoutout, but I don't think he'd be top 4.
The more I think about it, yo is probably right and Ngamer should be one of the four. The Show, the Stats Archive, the Guru site, and LOL X-Stats are all undeniably important contributions.
