So after the update today (7/9/2014), I've now twice received a different type of invite; it appeared in the lower left, on a pink background, and didn't actually show the sender. If clicked on, it would then show the sender, who I verified was nowhere in the area with me both times. This isn't strictly a complaint; I just can't find any information in the "Updates" section of the 3dxchat site about it as a new feature (or how to use it myself), so I'm asking here...has anyone else had this happen? Anyone know how to do it yourself? UPDATE: Apparently, this was/is the new "pay to mass invite people" option, which is available when you open a room, providing you have enough cash for it. So yeah. There it is.
