Hello welcome! There is a bit of a learning curve but if you managed to sign up, make a post and successfully save your keys you already did the hard part! Most steemians are pretty friendly if you need some help just ask! We also have some steem related discord chat groups, this one is for new users and one of the bigger off site communities http://minnowpond.org/ (Palnet / @minnowsupport)

Let me know if you have any questions!
