Hi.

We aren't sure if this is your site does but we are glad to see it.  There are a couple things we noticed and wanted to ask to improve if you're able.

1.  NewRewardCoin is using an app icon as a logo.  Using the normal round coin one instead would look better
like here: http://sumexplorer.com/images/logo.png

2. NewRewardCoin spelt SumCoin but the correct is Sumcoin with lowercase c

If you're in a position to help correct, we would appreciate it.
