Hi Ivana - We offer live chat support during US business hours for our Business Bundle customers. You can check out the bundle to see if it's the right fit for you:
I see that you already successfully mapped your domain yoursoulbeat.com by updating the name servers to NS1.WORDPRESS.COM, NS2.WORDPRESS.COM, NS3.WORDPRESS.COM.
If you map a .sk domain to your WordPress.com site, you'd need to do the same thing, logging into your .sk domain registry's control panel and setting your domain to use the same three name servers as above. If you have trouble with that part of the process, your domain provider can likely help you out.
You mentioned I can connect .sk domain to my 'blog using'. What about to my website using?
Domain mapping works exactly the same, whether you've set up WordPress.com as a blog or a website.
Lets say my new domain will be IvanaKormanikova.sk. So if someone in that country (Slovakia) serches for IvanaKormanikova.sk, will it take them to my website that will be also under domain YourSoulBeat.com and IvanaKormanikova.com?
That's right - both addresses will point users to the same site when visitors enter either one in their browser's address bar, as long as the mapping has been set up for both.
Just let us know if you need anything else.
