The difference between PALnet.io and Steem mystified many of us at first. The thing to note is that PALnet.io is a side-chain of the Steem blockchain, not a fork off it. That means:

• Anything posted to Steem will not appear on PALnet.io unless the #palnet tag is used.

• Anything posted to Steem with the #palnet tag will, indeed, appear on PALnet.io, too!

• Anything posted to PALnet.io will also appear on Steem.

So, it is perfectly understandable that you would want to introduce yourself there, too! I didn't fully realize the connection, either, until I made one post on Steem with the #palnet tag, and then made one post to Palnet.io and watched what happened in each case! 🙂

So, no harm, no foul! Keep on posting!
