Check UK or US Domain Names using Whois
Having your own Domain Name means that clients and customers can find you easily and remember your internet address without difficulty.
Your Internet provider or one of the many agencies can get your name registered for you.
It is a simple matter of them sending off an email for you, and sometimes replying to a query. The cost? Around 50-100 pounds.
The registration authorities also charge an annual rate, (unless you registered before these charges came in!)
Be careful that you have it in writing that you can move your Domain from the company which registered it without difficulty. This comes from painful personal experience!
The crooks and creeps have gone cyber like the rest of us!
