Well, the Forge has four different types of metalsmiths:

Blacksmiths, who work with iron, steel, and all manner of heavy metals to make things that are functional and sturdy
Whitesmiths, who work with silver to create beautiful pieces, be they artwork or weaponry
Redsmiths, who work with copper and brass, and who tend to incorporate mechanical elements into their creations
Yellowsmiths, who work with gold and are very precise when they craft

In addition to those smiths, our member tiers are all based on metals:

Bronze	Iron	Silver	Gold	Platinum	Obsidian
Cobalt	Mythril	Orichalcum	Adamantite	Titanium	Netherite

(This whole question roughly translates to, "Hey, here's some ideas for metals to incorporate into your entry. Hope it helps.")

Prestige is basically our equivalent of points. You earn them whenever you post content to the group, and from jams. The more prestige you gain, the higher level you are in the Forge, and the Forge Council is in charge of registering it and logging it in a list on the group page.

This jam only allows player skins, but they can be standard or HD resolution.
