Welcome to the Steemit world. I know about messing up the one chance to use that introduceyourself tag! I made a bad introduction and earned just a few cents. After learning lots about Steem, I told my nephew to read lots of introduction posts BEFORE making his own. He followed my advice and earned himself $60 on that one posting!

A word of caution: Be careful of all the promotion bots that want you to spend your money to be promoted. They might get you some exposure, but you basically give up all or more of your earnings to pay for it.

If you are interested in promoting your articles or have items that you would like to obtain or dispose of, there is the #happystore (looking to re-brand itself to more clearly define its services) that you may wish to use. Simply click on the tag (link) to find the latest version of it. It costs you NOTHING!

Wishing you the very best here on Steemit.
