User blog:Purplatypus/Let's Figure out Capitalization!

While a lot of capitalization questions are answered on the Guidance for Scribes page, there are a few terms that aren't specificied there that I keep noticing as I edit: Any thoughts on any of these? I'd like to reach a consensus then add them to Guidance for Scribes
 * 'gold' and 'silver' - usually not capitalized, which seems right to me--these terms are used in ways that aren't particularly specific to HabitRPG
 * 'gems' - as pointed out by Missyvecc on Talk:Gold Points, these arguably fit under the uncapitalized category of 'Names of other items that a player can possess several of."
 * 'cron' - probably a HabitRPG-specific enough meaning that it should be capitalized?
 * 'inventory' - in some ways this is a location in the game like The Tavern, meaning it would be capitalized, but it's also a general feature of RPG-type games...
 * possibly other things that I'm forgetting
