The URL written in the about section is incorrect

Hello, the URL( sferik.github.com/t ) in the about section is probably incorrect.


```
$ curl -v https://sferik.github.com/t
* Could not resolve host: sferik.github.com
* Store negative name resolve for sferik.github.com:443
* shutting down connection #0
curl: (6) Could not resolve host: sferik.github.com
$ dig sferik.github.com +short
```

Is sferik.github.io/t correct?
