hi there - don't worry your not alone - first go and introduceyourself - lots of help can be found there - and read the steemit white paper
when you write a post the tags at the bottom will be what category your post will end up in - see tags and topics to the right - look at what is hot - and what is trending and get a feel for what you want to write/say/share
try to always put a picture with your words - you can do this by linking said picture - as for voting - well thats an art in itself - look to google there are a few articles written about steem
steem has its own currency - you get these by upvoting people - i am new as well so can't really tell you more ...but explore others will be willing to help you
enjoy the adventure
Ahhh, thank you a lot unity1! That was really helpful, but not too long either. Heheh.
I think I'll like it here. Everyone I've met so far has been super friendly and kind, and I already feel very welcome.
Thank you for your guidance.
