Well. It seems you can read a message and reply to it. That's a big start. Next you have to make a post yourself :) Then figure out how to add pictures. Then a little text editing and your all set to make your presence known on hive.

Of course after that you'll want to figure out how to collect your hive cash. How to invest your hive cash and eventually how to cash out your hive money :)

Also... if you are interested in a mission let me know :) Hive is nice because I can send you coin directly in response to posts. Very useful
