Welcome to the steemit community @peter18!
We sincerely hope you find all that you are looking for here, and have found a new home here.
Six suggestions:
1. guard your passwords carefully, and only post with the posting key,
2. only use your active key for wallet transactions,
3. Master password is only for resetting new passwords,
4. do NOT lose your passwords; copy and store off line,
5. Don't post other people's work, whether photos or written without credit, and
6. when you open up your steemit.com, up in the upper right corner of the page is 3 bars. Click on those, and then on the "welcome", and you will get a whole lot of reading material that will help you.
I found you because @xcountytravelers and @brittandjosie of @heyhaveyamet featured and promoted your post to get more exposure and help you grow quicker.
If you find yourself overwhelmed and need some guidance, or you have any questions there are knowledgeable steemians available that can assist you; you can click to go to the Steem Terminal in Discord here:
Have fun and happy steeming!
