Hello All, I am new to creating SecondLife products, and am needing some assistance. Please note that I only have a Marketplace store. I have no inworld setup at all. I was invited to an event inworld to sell my products. My question is, how do I make it possible to sell my Marketplace items inworld? If there is a video I can watch, please let me know. Any help is much appreciated. Thank You, JaeleiAmare Resident
