my url ?

how would I find my URL, I wanted to look at a web site and it asked for my URL number or provider something like that, how would I know, what is it, I have seen it mentioned on here, what does it do, I know this seems like a wind up, but I was taught if you don’t know ask, so I am asking,

First thing is, do you have your own personal website, blog or some form of personal web space you access via www.whateveritiscalled.com?
If yes then you have a url, Uniform Resource Locater, if not then you probably don’t.

Were you looking at a blog, that you wanted to comment on? Some bloggers assume everyone else has their own blog and basically they want your url for it. Like exchanging postal addresses or phone number so you can be contacted.

no I don’t have anything like that, just a btinternet.com so I might not need to fill it in, thanks for that Colingl
