First off, congrats! (and added to my bookmarks)
You'll have to keep me informed about Hive (how to get there etc.)
Well dern, now I gotta write two answers LOL (or just cut and paste this one)
go to https://hive.io/
click on the "Hiveisalive" button
Use the same username and posting key from Steemit (posting key can be found on your steem wallet under "keys and permissions"
profit!
