You actually cannot do it just now @herbert-boss because transfers are down. You can do it internally. When it's up and running, you can go to your wallet, click on the drop down by your Steem Balance (not, there at the moment, but will be) click transfer, then send it to my name (hisnameisolllie), amount 0.001 Steem ($0.004) and then put your message in the memo.
