hello Steemians,
I want to thank @wilmer1988,@radjasalman,@event-horizon,@juichi for approving my previous achievement tasks.
Basics of Steemyy
Steemy is a website tool designed by @justyy. It is a Decentralized online application that works with the steemit Blockchain, providing Steemians with some basic account information and the means for accomplishing tasks like making and checking a delegation, auto claiming of rewareds and viewing vote.

1. What is Effective Steem Power? Tools- Steem Account Information
Effective steem power is the actual steem power in an account used for voting. In order for us to calculate Effective Steem power, we have to add a sum of personal Steem Power and all incoming Delegation and now minus it with all outgoing Delegation, now the remaining amount is Effective Steem power.

When you search Steemyy.com and click on Tools, then Account Information, you can view your effective steem power when entering your username.

2. How do you delegate SP using "Steem SP Delegation Tool"?

It is very easy to delegate SP to another account. We can do this by clicking on the tools icon in the website and clicking on Steem SP Delegation Tool. Then enter the Delgator(sender) and Deegatee(receiver) username and the amount of SP to transfer.

3. How do you check the Transfer History between any two Steem accounts using "Steem Wallet Tool - Steem Account Transfer Viewer"?

To check the transfer history between any two accounts, we can click on the Tools in it and then click on Steem Wallet Tool- Steem account Transfer viewer. Then enter all the account details and get the transaction details between two accounts.

4. How do you automate claiming STEEM or SBD without having to click claim button each time, using "Steem Auto Claim Rewards"?

In this website ,There is advanced option called Steem Auto claim Rewards to claim rewards automatically. The icon can be seen when we click on tools. We need to enter the steem ID and the posting key to the website. Then enter the duration of auto claim rewards as seen in the image shared.

5. How do you check the outgoing votes report for any specified period using "Steem Outgoing Votes Report"? (This is really an important and a beautiful feature of Steemyy)

This is one of the most used and most important tools on this site. You can check the votes that you given (i.e., Outgoing) to others by clicking on the tools icon and then Clicking on Steem outgoing Votes report and enter your username. All information about your votes is shown as a pie chart.

6. How do you check the incoming votes report for any specified period using "Steem Incoming Votes Report"?

Same as outgoing votes, we can check the incoming votes that we receive from others users, using this tool. A detailed pie chart with incoming votes percentages will be shown in the tool.

7. How do you check who has delegated SP to your Steem account or any Steem account using "Steem Power Delegator Checker"?

The Steem power delegator checker icon can be found in the tools icon in the website. You click on tools and check who has delegated you through the percentage in the pie chart.
