Delure

HI! So Im really new to SL, Iv tried several times to get going here but never did. I have the time now to serious get started so Id like to learn but its pretty overwhelming. I have experience modeling in Marvelous Designer and 3ds Max for IMVU. Iv been doing it for about 12 years now, so I don't need tutorials really on 3d modeling, just more on the SL side of things. Where to get started, what all these body shapes are, how to export and upload, the ins and outs of pricing, ,how to set up shop, etc. Are there any good tutorials yall can suggest, or even classes that are specific to clothing meshing and uploading?
