From my 6 years here, I've seen coders who have released mods that were way above what I would consider a top notch modification. In other words some of these people have gone above and beyond what one would expect for nothing and yet some of these mods could fetch some $$ if allowed to do so here. These people also support these mods through hundreds and hundreds of additional requests, members who are a few bricks shy of a full load, inexperienced forum admins and the list goes on and on.
And I remember who these guys are, and I'll never forget them, or thank them enough. How's that sound for an incentive?
