Ah Okay thanks for the replies.
So in summary, because I have now registered the domain and want to keep it - I should be Happy that I've opted out my address details (of which I am), but will just have to take it on the chin the fact that it reveals my full name, as the registrant?
Maybe there would have been ways around it - as suggested by previous posters above me - If I was still too buy the domain name, but as I've now gone ahead and registered the domain, it's too late.
Maybe i'm just being a little over-cautious, it's in my nature lol
I suppose if you've got nothing to hide, you shouldn't be too worried.
