So here's my review of steemworld.org:

First thing you need to do to open your dashboard is to search "steemworld.org/@username".
This will take you to your dashboard.

Dashboard

This is how your dashboard will look like.

Voting power:

Focus on the circled part in the image above, this is the voting power meter. This shows the different $ value at different percentages of voting. Mine is zero because my SP is not enough yet. The more your SP is the more power your vote will have.

If you scroll down a little you will see a number of options on the left hand side.

Stats

This option tells about your Steem power, your voting power, your resource credits , number of followers , number of posts etc.
This also shows your reward summary. The rewards you received in last 30days/7days/all time.

Balance

This option gives a brief look at your wallet status, about your STEEM, SBD, SP, Saving account etc etc. Basically you can perform all the wallet operations in the balance option.

Other options

The other options in the left corner tells about your followers , about market info i.e the steem price , SBD price and other info related to market.

If you scroll a little more there is a option to see your upcoming author and curation rewards which I find very useful as it gives all the information in one view. It tells you about your payout time, the amount of STEEM power and SBD you will receive.

Below Coming rewards section there is a section for tools.

This section provides the link for number of useful tools like Block Explorer, Change password , Account creator, Abuse finder etc etc.

I explored this site quite thoroughly and I find it very useful for having overview of my Steemit account.

Thanks @mariita52 for guiding me through task 1 of achievement 5, looking forward to the 2nd task.
