1) Create a Post on the STEEM Blockchain
This tool is using Steem-js JavaScript. I you can add up to 5 tags and custom permlink. If you want to add more tags, please request this in comments and I will send you link. But you can't edit post on steemit.com if it has more than 5 tags.
You need to use your posting key. DO NOT USE YOUR ACTIVE KEY.
2) Delegate Steem Power
You need to fill up the form. To undelegate you need to delegate 0 SP or VESTS. Your SP will be locked for 7. This is Steem network rule.
Users have the option to delegate Steem Power to other users. When a user is delegated Steem Power - their bandwidth, content votes, and curation rewards are calculated as if it were their own Steem Power. Users are not able to power down or cash out delegated Steem Power however, as it still belongs to the original owner.
This tool is using SteemConnect, so your active key is safe.
3) Power Up Steem
Powering up - If you have STEEM tokens, you can Power Up to Steem Power to get more voting influence on posts and comments. Having more Steem Power also increases the amount of curation rewards and interest that you can earn. More SP also grants more influence on approving Steem witnesses.
You can use this tool to power up STEEM to STEEM POWER.

4) Vote For Witness
The Steem blockchain requires a set of people to create blocks and uses a consensus mechanism called delegated proof of stake, or DPOS. The community elects 'witnesses' to act as the network's block producers and governance body. There are 20 full-time witnesses, producing a block every 63-second round. A 21st position is shared by the backup witnesses, who are scheduled proportionally to the amount of stake-weighted community approval they have. Witnesses are compensated with Steem Power for each block they create.
You can see to 400 witnesses at Steemian.info.
You need to fill up form and enter active key at SteemConnect website.
