Please advise the format of a web address in the article submission box?

Possibly you're not writing the title in the right box. In the hub title, you need only write the name of your hub and hub pages does the rest. There are allowable characters and non allowable characters and I fear you may be using a mixture of both.

Just write the name - ie, My hub and in the unique address field you will see that hub pages stores it differently.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
