Hello there,

I am the creator of NimiqScan, and want to get some connection to the official people.
Unfortunately, I cannot even get an email from any Nimiq official websites i known, so I open this issue to introduce a little about the project.

NimiqScan is a blockchain explorer aimed to be easy, beautiful and fast, also we provides some tools and analytics to help people understand more about this blockchain. For example we have Transaction Decoder, Identicon Generator and some other cool stuffs. Also we support both English and Chinese, Mainnet and Testnet.

It would be very nice if you can add this project to the community website, or have some links in official websites. Also would like to hear more about the suggestions.
