IRL Stickers
With IRL Stickers every person, landmark,
coffee shop, lamppost, statue, or bus also has
a Basement to chat in. Stick them anywhere!
Everything you might want to know about CollectorRoom
CollectorRoom is Basement reframed for collectors. Basement is a multiplayer browser where every webpage becomes a live chat room. On collector marketplaces like TCGplayer, eBay, PWCC, Goldin, and COMC, you see who else is looking at the same listing in real time and can chat while prices move.
