Thank you soooo much Heather and Elayine for your advice! I'm making a to-do list right now, every single bit of perspective really helps.
Elayine, the important thing is not get overwhelmed. Pick one thing, say facebook page,twitter, about, pictures & focus on it for a couple of days-then move on to the next. Ask lots of questions, find teams, be present of the forums- you'll learn something new every time.
Here's a link that a kind soul shared on the forum. I go back to it all the time because it puts confusing info into easy to understand terms-made a lot of sense out the madness for me, lol
