One nice feature of Steemit is that you can delegate your power to some other members - so in short you rent it out for min. 7 days. It is a nice way to support your beloved friends or bots here on Steemit while you anyway not use it, sensational!
But how you do that.... Vessel is the answer!
Say Hello To Vessel - The Steemit GUI Desktop Wallet!
In early days it was more difficult to operate with Steem network as you need some command line tool, thanks to user GUI wallet it is easy now. Simple import your account and you can delegate Steempower to other users, when immediately cancel delegation it will come back in 7 days - easy as that!
If you asked already what is the (+ XYZ Steempower) in your account wallet page when joined.... well simple delegated SP from Steemit Inc. what is needed for account creation. :)
Here the Delegation page screenshot in Vessel:

I hope it helped you to understand the Steemit blockchain little more - feel free to test the feature at my new (poor) bot friend for Austria... - thx
