Lots of great advice listed above! In my experience starting on MFC, people were mostly nice to try and help me figure it out while I was first streaming. (even though I had done a bunch of research before hand to try and understand how to get things set up - it all seemed to spaced my mind once I was live. so definitely helps having some kind members help walk you thru some things)
I think aiming to make connections during the "new model" status can be beneficial. I have a small but solid group that have been watching me since I started - and they enjoy watching the evolution. There is a podcast called CAM101 that has some advice on engaging with your room and building regulars.
The podcast has helped me get some ideas of how to approach closing deals or getting more involvement in a dead public chat - might be something to listen to while you get ready
Sure you will do great! Goodluck!
