Steampunk Showcase?

I don't normally look at the "Showcase" tab under Search, but I happened to do so tonight, only to find quite a number of Victorian and/or Steampunk vendors listed, including:

• Mako Magellan
• Grim Brothers
• BlakOpal (somewhat misspelled as "Black Opal")
• RFyre/Silent Sparrow/Bare Rose (okay, not really Steampunk, but popular in these parts)

and, though not a vendor and perhaps not really Steampun, but a fellow traveler,

• Immersiva

Good to know these fine folk are getting some recognition, even if I still can't figure out how that tab is compiled!
