yes this would be a good idea. name suggestions - "The Helpful Polycounters" or "Polycounters to the Rescue!" Dunno if they are good names but they are half-serious suggestions :)
So some poor schlub has to surf every corner of polycount, scour it for the golden bits so you don't have to? That's a lot harder than just busting through the WAYWO thread. Also the kinds of gold that you're asking for don't drop on a regular basis.
Tldr: Theres always hope! In the last polycount upgrade thread this was discussed and i think something is gonna happen. May just be the tagging system they're planning on using, an then just add another to mark gold or something. A idea to save on admin work would be; "Featured post" tag on a post marks it as awesomesauce…
