For instance: Steemworld.org/@lghazal. It will redirect me to my dashboard ,@lghazal.
The next step is to look at the the stats tab, and then simply scroll down to find the reward summary for All Time, Last 30 Days and Last 7-days. I’m illustrating it in the screenshot below for your help:

Explanation of Delegations, types of Delegations and how to Delegate SP?

The temporary transfer of a user's Steem Power (SP) from one account to another is called delegation on steemit. If a user is delegating Steem power(SP) to someone,the user is effectively lending steem power to them.

Types of Delegation

The types of delegation which exists on the steemit platform are :-

• Incoming delegation : In this type of delegation, the user receives delegation from another user .

• Outgoing delegation : In this type of delegation, one user delegates SP to another.

How to delegate SP ?

The first step to delegation is to visit steemworld.org/[@your username], e.g. steemworld.org/@lghazal. Then we have to simply login to our Steemworld.org dashboard.
Then these are the steps to be followed:
Step 1: After visiting the page while we are still logged in we have to click on the Delegations tab,

Step 2:On the top right corner we have to click on Delegate, here you will be presented with your total SP and the input area .
Step 3:Now we have to put in the username of the SP recipient, and the amount of SP to be delegated.
Step 4: The last step is to confirm your delegation by clicking "yes" for delegation request to be executed.( I don’t have enough to transfer that’s why I can’t show the last step in a screenshot)
