When I registered my domain name I opted for the non-www format. I didn't really give it any thought. I didn't realise WordPress defaulted to www and don't even know if it's an issue. Certainly, my hosting provider says it isn't. However, what I have is a domain registered as wilsonsdance.co.uk with wordpress showing it as http://www.wilsonsdance.co.uk. I'm new to all this and it only really came to light when I registered with Google Webmaster to upload my sitemap which does seem to be processing - somewhat slower than I had expected but it isn't erroring. Do I need to align everything and if so how do I do it without causing me any problems.
